The DSA Roadmap ## A Clear Path Through DSA Mentor-led stages, each ending with interview-style problems and a contest set. STAGE 01 ### Foundations & STL Time complexity, arrays, strings, the STL containers and basic problem patterns. STAGE 02 ### Linear Structures Linked lists, stacks, queues, hashing and two-pointer / sliding-window techniques. STAGE 03 ### Trees & Graphs Recursion, binary trees, BSTs, heaps, graphs, BFS/DFS and shortest paths. STAGE 04 ### DP & Interviews Greedy, dynamic programming, contest practice and mock technical interviews.

That's a **set**. A hash table? **unordered_map**. A min-heap? **priority_queue**. In C++ these are one line, which is exactly why it dominates [competitive programming](/c-plus-plus-for-competitive-programming) and is the safe choice in any [placement coding round](/c-plus-plus-for-placement-preparation). ### Understanding, then speed We don't just teach you to call STL functions — you build the structures first so you understand how they work, then use the STL for speed. That combination of **deep understanding and fast implementation** is what separates students who clear interviews from those who freeze. New to C++?

The way they built each structure first, then showed the STL shortcut, made it finally make sense. Cleared 2 coding rounds." Aman V.Final-year · placed★★★★★ "The interview-style problems every class are gold. I stopped memorising and started actually solving." Priya R.3rd-year CSE★★★★★ "Best DSA course I tried — small batch, real code review, and a clear roadmap from arrays to DP. My Codeforces rating climbed fast."

Book a Free DSA Demo Class Good To Know ## Frequently Asked Questions What does the C++ DSA course cover?+ The course covers the full Data Structures & Algorithms syllabus in C++ — arrays, strings, linked lists, stacks, queues, hashing, recursion, trees, graphs, sorting and searching, greedy techniques and dynamic programming — implemented with the STL, with interview-style problems throughout. Why learn DSA in C++ specifically?+ C++ is fast and its Standard Template Library gives you ready-made data structures — vector, map, set, stack, queue, priority_queue — so you implement algorithms quickly and cleanly. It is the most popular language for [competitive programming](/c-plus-plus-for-competitive-programming) and is accepted in nearly every placement coding round. Do I need to know C++ before joining the DSA course?+ A basic working knowledge of C++ (syntax, loops, functions, OOP) helps. If you are new or rusty, we begin with a fast Core C++ and STL refresher — or start with [C++ for beginners](/c-plus-plus-for-beginners) — and place you in the right batch after a free demo. Is this DSA course good for college placements?+ Yes — it is built for it. The syllabus mirrors what interviewers ask in coding rounds, and the track includes problem-solving patterns and mock interviews so you can clear product-company and campus placements. See our [placement-prep track](/c-plus-plus-for-placement-preparation). How much does the C++ DSA course cost?+ Group classes start at ₹1,499 per month for 2 classes a week. A Mini Batch of 3–4 students is ₹2,499 per month, and 1-on-1 mentoring is ₹4,999 per month. A free demo class is available first. Are the DSA classes live with practice problems?+ Yes. Classes are live in small batches with a mentor who reviews your code, and every topic comes with hand-picked practice problems and contest-style questions, all recorded for revision. --- *Canonical: https://learn.modernagecoders.com/c-plus-plus-dsa-course*
