Mapcreator for the simple sidescroller (SDL) - mapcreator.h

//This example program is created by thecplusplusuy for demonstration purposes (no video about this, I think, it's too simple, and not show nothing new, but I put the source up, to make a complete program with the simple sidescroller (there is video about that)). It's a map-creator for the simple sidescroller game.

//Free source, modify if you want, LGPL licence (I guess), I would be happy, if you would not delete the link
//so other people can see the tutorial
//this file is mapcreator.h
#include <SDL/SDL.h>    //for the 2D graphics
#include <fstream>      //for write the finished map to a file
#include <iostream>     //for write out error (only for test purposes, probobly, it's not need anything else)
#include <vector>           //to store the map
#include <cstdlib>      //for the random number generation
#include <ctime>            //for seed the random number generator (it seems, that Linux is not need this header file for time(0)
#include <cstring>      //and the simple C-style string handling
