C++ Tutorial

Learn C++, a fast, powerful language with object-oriented and generic programming, used for games, systems and competitive coding.

C++ was developed by Bjarne Stroustrup at Bell Labs starting in 1979, originally as "C with Classes". It's a superset of C (with minor exceptions) that adds classes, templates, exceptions and the Standard Template Library (STL).

First C++ Program

C++

#include <iostream>
using namespace std;

int main() {
    cout << "Hello, C++!" << endl;
    return 0;
}

Hello, C++!

C vs C++

C	C++
Procedural	Procedural + object-oriented + generic
No classes, no function overloading	Classes, overloading, templates
`printf/scanf`	`cout/cin` streams
`malloc/free`	`new/delete`
No references	References (`int &r = x;`)
No exception handling	`try/catch/throw`
