Learn C and C++ side by side, from the basics to memory, data structures and modern C++. Every lesson has code you can run. Follow a path, then practice with challenges.
Follow a path: short lessons first, then a challenge to check you can use the idea on your own.
From your first program to operators, conditions, loops, strings, arrays, functions and structs, with a challenge after each topic.
Classic beginner exercises on numbers, text and arrays, solved in both C and C++, each with a challenge to try on your own.
Pointers, pointer arithmetic, dynamic memory and RAII, the parts that make C and C++ different.
Stacks, queues, hash tables, binary search and merge sort, each followed by a challenge.
Searching, sorting, recursion and bit tricks, implemented side by side in C and C++.
Overloading, lambdas, templates, the STL, classes and RAII: the tools that make C++ more than C.
Compare the smallest complete C and C++ programs.
