Programming Academy
Learn C++ with a real compiler right on the page: cout and cin, decisions and loops, arrays, vectors and strings, functions and references, then classes, inheritance and templates. Then put it all together in projects.

What C++ is, the parts every C++ program has, and your first programs: print words and numbers with cout, write comments, and read what the compiler tells you when something's wrong.
Keep values in variables (int, double, char, bool, string), do sums with them, and read what the user types with cin and getline.
Let a program choose: if and else, comparing values, && and ||, else if chains, and switch for many choices.
Do things again and again: while, for and do…while, with break and continue, and loops inside loops.
Keep many values under one name: arrays, then vectors that grow, the range-based for, totals, the biggest and searching.
Text with the string type: joining and comparing, length and letters, find and substr, reading whole lines, and reversing.
Make your own functions: values in and answers out, references that change a variable, overloading and default values, and recursion.
Group data and what it does: structs, classes with public and private parts, constructors, member functions, and vectors of objects.
Build on classes: inheritance, virtual functions, and templates, then put it all together in projects.
