C and C++ Roadmap

Low-level control and speed: pointers, memory, the STL and modern C++ for competitive coding and systems roles.

8 milestones · ~126 hours total

1. 1

   C basics

   ~10h

   Compile with gcc, types, operators, control flow, functions and the preprocessor.

2. 2

   Pointers and memory

   ~16h

   Pointers, arrays, strings, malloc/free, stack vs heap, and spotting leaks and dangling pointers.

   Practice this →
3. 3

   Structs, files and the build

   ~10h

   Structs, unions, file I/O, headers, Makefiles and debugging with gdb.

   Practice this →
4. 4

   C++ object model

   ~16h

   Classes, constructors and destructors, RAII, inheritance, virtual functions and operator overloading.

   Practice this →
5. 5

   The STL

   ~16h

   vector, map, unordered_map, set, priority_queue, algorithms and iterators, with complexity of each.

   Practice this →
6. 6

   Modern C++

   ~14h

   Smart pointers, move semantics, lambdas, auto, constexpr and the rule of five.

   Practice this →
7. 7

   Templates and concurrency

   ~14h

   Function and class templates, std::thread, mutexes and atomic basics.

   Practice this →
8. 8

   Problem solving in C++

   ~30h

   Use the STL to solve contest and interview problems quickly and cleanly.
