(C++) function definition

A function definition is consists of (a copy of) a function declaration and this function's body.

Function definitions are commonly found in implementation (.cpp) files.

#include <iostream>

void SayHello()

{

std::cout << "Hello\n";

}

The first line of the function SayHello is (a copy of) the function declaration. The part between the accolades is the function body.
