I've created a minesweeper game in C for a school project of mine and I decided to upload it here.Of course it needs to be compiled first since below there's only code.

#include<stdio.h>
#include<stdlib.h>
#include <ctype.h>
#include <math.h>
#include <time.h>

#define dimensions_small_table 15
int tile_choiceX,tile_choiceY,gbl_current_round=-1,gbl_mines=-1,tile_revealed_small_table[dimensions_small_table][dimensions_small_table],tile_checkZeros_small_table[dimensions_small_table][dimensions_small_table]; //global variables for small table
char gbl_Small_table[dimensions_small_table][dimensions_small_table],gbl_gameEnd='A';

int main()
   {
	int gotostart;
    char menu01sel,choice01;
    printf("Welcome to Minesweeper Game!\n");
    do
      {
	   gotostart=0;
       printf("Press 1 to start playing!\n");
       printf("Press 2 for information\n");
       printf("Press 3 for legend\n");
       printf("Press 4 to exit\n");
       do
       { menu01sel=getch(); } 
       while (menu01sel!='1' &amp;&amp; menu01sel!='2' &amp;&amp; menu01sel!='3' &amp;&amp; menu01sel!='4');
       switch(menu01sel)
       {
        case '1':
	       SmallTableGame();
           break;
        case '2':
           HelpFunction(); 
           gotostart=1; 
           break;
        case '3':
           printf("\nLEGEND: *=tile not revealed,E=tile empty,B=tile has bomb\nNumber(1,...,8)=the number is equal to the amount of bombs at the nearby tiles\n\n");
