C and C++ interview practice
C and C++ Coding Interview Practice
Switch between C and C++ while practicing interview questions on pointers, memory, data structures, algorithms, object-oriented programming, STL, and systems concepts. Each generated starter template is normalized for the selected language and ready to complete.
What you will practice
The C path emphasizes arrays, character buffers, structs, pointer arithmetic, dynamic allocation, function pointers, and careful resource management. The C++ path adds classes, RAII, smart pointers, templates, move semantics, containers, algorithms, and modern language practices.
Progressive sessions combine implementation with explanation. AI feedback checks the selected language, code structure, likely edge cases, complexity, and memory behavior, while theory panels provide examples that connect the current problem to reusable interview patterns.
- C syntax, arrays, strings, structs, and file I/O
- Pointers, allocation, ownership, leaks, and memory safety
- C++ classes, constructors, destructors, inheritance, and polymorphism
- STL containers, iterators, algorithms, templates, and lambdas
- Linked structures, trees, graphs, dynamic programming, and bit operations
- RAII, smart pointers, move semantics, concurrency, and performance
How a practice session works
Step 1
Choose a difficulty, topic, or targeted plan. The engine creates an interview-style prompt with the context and constraints needed to reason about a correct solution.
Step 2
Write and run your answer in the browser. Ask for a focused hint or theory explanation when you need help without immediately revealing the final answer.
Step 3
Review semantic feedback, complexity notes, examples, and the reference approach. Automatic checkpoints preserve the latest question and code for your next visit.
