Header Files (test.h)

Introduction

Dynamically Linked Library has 3 parts

• Header File - .h
• Library File - .lib
• Binary File - .dll

What is header file

Header file is a list of function that a library provides , it doesn't tell what the functions do it just declares them

example if you open sdl.h you would see something like

int SDL_Init(int flags);

This declares SDL_Init() function but it doesnt tell what it does

How to use

just at top of your code mention

#include <SDL2/SDL.h>

here SDL2 is directory where SDL.h is stored
