STARTING POINTS

Pick one useful route.

A roadmap is a sequence, not a race. Finish one small route before spreading attention across many topics.

2

Learning C++ for coursework or competitive programming

Begin with compilation, then practise values, control flow, functions, arrays, pointers, and classes in order.

3

Building problem-solving skill

After one language foundation, study data structures, complexity, arrays, linked lists, and stacks. Write and trace tiny implementations.

4

Preparing for core CS interviews

Pair DSA with operating systems, databases, and networks. Explain a trade-off aloud after each lesson.

5

Beginning system design

Learn requirements before components, then study caching and its freshness trade-offs. Do not skip fundamentals simply because a diagram looks familiar.
