Hello guys :) What a great and usefull forum m8s :)
I have made a program in snake, but i have remade it, because c++ is quite new for me, but on tursday i have to do a presentation(examination) for my teacher explaining the code, i understand 80-90 % of the code. But i would like to have, a pro explaining each section function if possible :)
The code:
#include <stdio.h>
#include <stdlib.h>
#include <windows.h>
#include <conio.h>
#include <mmsystem.h>
#pragma comment(lib,"Winmm.lib")

void control(int &direction);
void move(char main[][75], int &pieces, int pastCounter, int past[][2], int &dots, int &score, int &exit);
