> C++ for kids, honestly: who is ready for it and who should start with Python, three short C++ programs to run, and how C++ leads to USACO for US students.

In short

C++ can be a child’s first typed language from about 11 or 12, if they read and type comfortably and do not mind strict error messages; for children of 9 or 10 we recommend starting in Scratch or Python and moving to C++ later. Free compilers such as g++ and Clang, or an online compiler page, are all a beginner needs. Modern Age Coders teaches this live online for US students, in a batch or one to one, and the first class is free.

Learn it with a teacher

## Three courses on the road to C++

C++ for Kids covers ages 9 to 12, C++ for teens takes over at 13, and Python suits a child who wants a gentler first language.

Is my child ready?

## Is C++ a good first language for your child?

The official C++ site asks beginners who have never programmed, "why not learn in modern C++?" For teenagers we agree. For younger children the answer depends on the child, so here is the table we use with parents.

| Age | Usual starting point | When C++ makes sense |
| --- | --- | --- |
| 6 to 8 | Scratch or other block coding | Not yet; typing and reading speed get in the way |
| 9 to 10 | Scratch, then Python | Rarely as a first language; a few C++ ideas after a year of Python |
| 11 to 12 | Python, or C++ with a patient teacher | Yes, for a child who types well, reads errors calmly and wants it |
| 13 and up | C++ directly is fine | Yes; our teen course starts from zero |

### When C++ is a good choice

A child who wants to compete is the clearest case. USACO, the USA Computing Olympiad, accepts C, C++, Java and Python, and says C++ is the only language supported at the International Olympiad in Informatics.

It also suits children who like knowing how things work underneath: why a number has a limit, where memory goes, why one program runs faster than another. C++ makes those questions visible.

### When it is not

If your child wants to see something on screen within ten minutes, C++ is a slow start. Python, Scratch or JavaScript give quicker rewards, and quick rewards keep young beginners coming back.

If their goal is websites, apps or AI, C++ is the long way round. Those children do better in JavaScript or Python, and can still learn C++ later for competitions.

For a side-by-side view of languages by age, see our post on [coding languages for ages 10 to 18](/blog/best-coding-languages-kids-10-18-beginner-advanced) and our guide to the [right age to start coding](/best-age-to-start-coding).

Setting up

## What a child needs to write C++ at home

The tools are free. The official site, isocpp.org, lists free compilers for every major operating system and several online compiler pages for computers where nothing can be installed.

| Computer | Free option isocpp.org lists | Note |
| --- | --- | --- |
| Windows PC | Visual C++ Community, or a Windows build of GCC (g++) | Microsoft’s compiler is described as free for Windows |
| Mac | Clang | Described by isocpp.org as an open-source compiler for various platforms |
| Linux | GCC or Clang | isocpp.org says builds are likely available through the package manager |
| Chromebook or school laptop | Online compiler pages such as godbolt.org, Wandbox or ideone.com | Some only compile; others also run the program and show its output |

### Which C++ is "modern" C++?

C++ is an ISO international standard, and its committee publishes new versions over time. The isocpp.org status page says C++23 has been published and work is under way on C++26.

For a child, the version matters less than the style. Modern C++ uses std::string, std::vector and the random library instead of the older C habits, and that is what every program on this page uses.

### Books, if your child likes them

isocpp.org recommends books for complete beginners, including an introduction to programming written by the creator of C++ and a shorter Tour of C++ by the same author. Both are written for adults and older teens.

For younger readers, we suggest a teacher and short programs first, then a book once they can already read simple C++ comfortably.

Real code

## Three short C++ programs for a first month

These are the first three programs our C++ beginners write. They use only standard C++ described on cppreference.com. Paste each into an online compiler or a compiler on your computer and run it.

***Program 1 · say hello**c++*

```
// hello.cpp (ours)
#include <iostream>
#include <string>

int main() {
    std::string name;
    std::cout << "What is your name? ";
    std::cin >> name;
    std::cout << "Hello, " << name << ". Welcome to C++.\n";
}
```

There is no return statement, and that is allowed: cppreference says that reaching the end of main without one has the effect of return 0. std::cin reads from the keyboard, the standard input.

***Program 2 · a guessing game**c++*

```
// guess.cpp: a number guessing game (ours)
#include <iostream>
#include <random>

int main() {
    std::random_device rd;          // a seed source
    std::mt19937 gen(rd());         // the random engine
    std::uniform_int_distribution<int> pick(1, 50);

    int secret = pick(gen);         // 1 to 50, both ends included
    int guess = 0;
    int tries = 0;

    while (guess != secret) {
        std::cout << "Guess a number from 1 to 50: ";
        std::cin >> guess;
        tries = tries + 1;
        if (guess < secret) std::cout << "Higher\n";
        else if (guess > secret) std::cout << "Lower\n";
    }
    std::cout << "Got it in " << tries << " tries.\n";
}
```

uniform_int_distribution produces whole numbers on the closed interval from a to b, so 1 and 50 can both be the secret. Our arithmetic: halving the range each time finds any number from 1 to 50 in at most 6 guesses, because 2 to the power 6 is 64, which is at least 50.

***Program 3 · scores in a vector**c++*

```
// scores.cpp: why .at() is the safer way in (ours)
#include <iostream>
#include <stdexcept>
#include <vector>

int main() {
    std::vector<int> scores = {7, 9, 4};
    scores.push_back(10);           // positions 0, 1, 2 and 3

    std::cout << "First score: " << scores.at(0) << "\n";
    std::cout << "How many: " << scores.size() << "\n";

    try {
        // there is no position 4
        std::cout << scores.at(4) << "\n";
    } catch (const std::out_of_range& e) {
        std::cout << "Caught it: no score at position 4\n";
    }
    // scores[4] also compiles, but reading it is undefined behavior
}
```

vector::at checks the position and throws std::out_of_range when it is outside the vector. The square-bracket version does no check, so the program in the last comment would compile and then behave unpredictably.

### What the guessing game teaches

The while loop keeps asking until the guess equals the secret; the if and else if decide which hint to give. That is a complete game in under twenty lines, and every line is something the child can explain.

The halving strategy is the real lesson. A child who works out that 6 guesses are always enough has discovered binary search, an idea that appears in competitions for years to come.

### Why we teach .at() before [ ]

Beginners make off-by-one mistakes constantly: a vector of 4 scores has positions 0 to 3, not 1 to 4. With .at(), that mistake produces a clear error the child can find. With square brackets, it can produce nonsense that looks like a working program.

Once a student can always say which positions exist, we show them square brackets and why experienced programmers use them in fast code.

Limits and bugs

## The C++ lesson other languages skip: every number has a limit

In Python, whole numbers grow as big as needed. In C++, each type has a fixed width, and going past it is a bug the language does not have to catch. Children find this strange at first and fascinating soon after.

| Type | The standard guarantees | Usual today |
| --- | --- | --- |
| short | At least 16 bits | 16 bits |
| int | At least 16 bits | At least 32 bits on 32-bit and 64-bit systems |
| long | At least 32 bits | 32 or 64 bits, depending on the system |
| long long | At least 64 bits | 64 bits |

### A worked example: the overflowing score

Our example: a game stores the score in a 32-bit int, which can hold up to 2,147,483,647. If the game adds 1,000 points every second, the score passes that limit after about 2,147,483 seconds, and 2,147,483 / 86,400 is about 24.8 days of non-stop play.

After that, signed integer overflow is undefined behavior. cppreference lists it among its examples, alongside reading outside an array, and says of undefined behavior: "There are no restrictions on the behavior of the program."

### What a child takes from this

The fix is simple, a long long, which the standard guarantees is at least 64 bits. The habit is the valuable part: asking how big a value can get before choosing its type.

USACO makes the same point in its instructions: answers usually fit in a standard 32-bit integer, but this is not guaranteed. Checking limits before coding is a habit we teach from the first month.

Where it leads in the US

## From a first C++ program to USACO

For American students, C++ has one very concrete destination: the USA Computing Olympiad. Its contest instructions explain how languages are treated.

| Point | What USACO says |
| --- | --- |
| Fee | "There is never any fee for participation." |
| Languages | Solutions in C, C++, Java or Python |
| At the international level | "C++ is the only language supported at IOI" |
| Time limits | For most contests, 2 seconds per input case for C and C++, 4 seconds for Java and Python |
| Python at the start | All bronze-level problems are meant to be fully solvable in Python |
| Divisions | Bronze, silver, gold and platinum |

### What this means for a 12-year-old

A child does not need C++ to start USACO. Bronze can be done in Python, so a younger student can compete in the language they already know and switch when the problems demand speed.

USACO also says that on some problems, particularly in higher divisions, Python may be too slow to solve every input in time. That is the point where C++ pays off, and a student who learned it at 12 or 13 is ready for it.

### Our part in it

Our [USACO preparation coaching](/usaco-preparation-online-coaching) takes students from their first contest upward. We are not connected with USACO, and we make no promises about divisions or results.

Teens who prefer building to competing can take C++ toward graphics and games instead; our page on [C++ game development](/c-plus-plus-game-development) covers that route.

A first term

## Twelve weeks of C++ for an 11 to 13 year old

Our outline for a younger student who is ready for C++. Teens in our main course move faster; younger children may spend longer on the first weeks.

| Weeks | What the student builds | The idea |
| --- | --- | --- |
| 1 to 2 | Hello, a calculator, a mad-libs story | Compiling, variables, input and output |
| 3 to 4 | The guessing game, then a dice roller | Loops, conditions, random numbers |
| 5 to 6 | A times-table quiz that keeps score | Functions and return values |
| 7 to 8 | Scores and names in vectors | Vectors, .at() and off-by-one thinking |
| 9 to 10 | A text adventure with rooms | Strings, menus, larger programs |
| 11 to 12 | Two small olympiad-style problems | Reading a problem, testing edge cases |

### Ages 9 to 10

C++ for Kids at a slower pace, with more time on typing carefully and reading what the compiler says; some children try Python first.

### Ages 11 to 12

The twelve weeks above inside C++ for Kids, in a batch or one to one, with a lot of time on reading error messages.

### Ages 13 and up

Our C++ for teens course, from first programs through the STL and data structures to games and competition problems.

Growing into C++

## Four stages of a young C++ programmer

The stages we teach through, and what comes next.

| Stage | What it looks like |
| --- | --- |
| 1. Copier | Types out programs carefully and hunts down missing semicolons |
| 2. Reader | Can explain what each line of a short program does |
| 3. Builder | Writes small games and tools from an idea, with loops and vectors |
| 4. Solver | Reads a contest problem, plans, and checks limits before coding |

### For parents

Compiler errors are long and frightening at first. A child who reads the first line of the error, not the whole wall, has already reached stage 2.

Ask your child what the largest value in their program could be. If they can answer, they are thinking like a C++ programmer.

### For kids

Fix the first error first. One missing semicolon can cause ten errors further down.

Run the program after every few lines. Small steps make bugs easy to find.

Questions from parents

## C++ for kids: common questions

### Can kids learn C++?

Yes. A child can learn C++ from about 11 or 12 if they read and type comfortably. For children of 9 or 10 we recommend starting with Scratch or Python and moving to C++ once they understand loops and variables.

### Is C++ too hard for a 10 year old?

In our view it is a harder first language than a 10 year old needs, because of strict syntax and long error messages. A year of Python first usually makes C++ much easier.

### Should my child learn Python or C++ first?

We usually recommend Python first. Choose C++ first if your child is 12 or older and aims at competitions such as USACO, or wants to understand how computers handle memory and speed.

### Is C++ free to learn?

The tools are free. isocpp.org lists free compilers such as GCC (g++), Clang and Visual C++ Community, plus online compiler pages that run in a browser.

### Can my child write C++ on a Chromebook?

Yes, using an online compiler page such as godbolt.org, Wandbox or ideone.com, which isocpp.org lists. Some only compile code; others also run it and show the output.

### What version of C++ should kids learn?

Modern C++. The isocpp.org status page says C++23 has been published and work is under way on C++26. For beginners, the style matters more than the version number.

### Do you need C++ for USACO?

Not at first. USACO accepts C, C++, Java and Python, and aims for every bronze problem to be fully solvable in Python. It says C++ is the only language supported at the international olympiad, so serious competitors usually learn it.

### What is the first C++ program a child should write?

A short program that asks for their name and says hello, then a number guessing game with a loop. Both appear on this page, written in standard C++.

### Do you offer a C++ course for kids under 13?

Yes. C++ for Kids is for ages 9 to 12, in a batch or one to one, and C++ for teens continues from 13. Some younger children start with Python or Scratch and move across.

### What times are classes for US families?

Weekdays or weekends, flexible. Choose your batch, or for a very personalised plan choose 1-on-1 at your convenience, weekend mornings or weekdays.

### How much are C++ classes?

The first lesson is free. Then families pay monthly for the teaching, and the fees section of this page shows the amount in US dollars.
