cpp reference for header files code example
Example 1: c++ include header
#include "headerfile.h"
Example 2: c++ header files
class vec2 {
public:
void printVec();
float x, y;
}
#include "vec2.hpp"
void vec2::printVec() {
std::cout << x << y << std::endl;
}
Example 3: c++ header files example
#ifndef TOOLS_hpp
#define TOOLS_hpp
#include<vector>
#include<iostream>
#include<fstream>
#include<string>
using std::ifstream;
using std::cout;
using std::cin;
using std::endl;
using std::cerr;
using std::vector;
using std::string;
inline vector<int> merge(const vector<int>&a,const vector<int>& b);
std::vector<int> sort(size_t start, size_t length, const std::vector<int>& vec);
#endif
Example 4: including cpp header file in c++
#include "enter_name_here.cpp"
