c++ why use header files code example
Example 1: c++ header files
// You should use header files when you wan't to split your
// program across multiple files. Use it like this:
// vec2.hpp
class vec2 {
public:
void printVec(); // Decleration
float x, y;
}
// vec2.cpp
#include "vec2.hpp"
void vec2::printVec() { // Implementation
std::cout << x << y << std::endl;
}
Example 2: including cpp header file in c++
#include "enter_name_here.cpp"
//Make sure the files are in the same directory.
