Bassicly my code is supposed to be taking ints from int tt[] in main()

const int tt[] =
    {
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0,
0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0,
0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0,
0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0,
0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0,
0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0,
0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0,
0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0,
0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0,
0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0,
0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0,
0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
    };

The program then is exposed to give cordinates for a vector based on its sequential order and give cordinates for the texture if its gives #1. Based on my cout statement tiletype = tt[count]; I can tell the program crashes after reading the fith zero from int tt[] and gives the error Vector Subscript out of Range.

I assume the problem fall under this section of my code:

  for(x = 1; x < c;++x)
    {
    for(y = 0; y < r;++y)
    {
        tiletype = tt[count];
        cout <<tiletype<<", ";
            vertices[a].position = sf::Vector2f((0+y)*ts,ts*(x+1)+80);
            vertices[b].position = sf::Vector2f((0+y)*ts, (0+x)*ts+80);
            vertices[d].position = sf::Vector2f(ts+(y*ts),(0+x)*ts+80);
            vertices[e].position = sf::Vector2f(ts+(y*ts), ts*(x+1)+80);
            vertices[a].texCoords = mapcords(tiletype,0);
            vertices[b].texCoords = mapcords(tiletype,1);
            vertices[d].texCoords = mapcords(tiletype,2);
            vertices[e].texCoords = mapcords(tiletype,3);
            a += 4; b += 4; d += 4; e += 4;count++;
    }
    row += 1;
    cout <<endl<<"Row "<<row<<": "; y = 0;
    }

This is the rest of the code.

#include <SFML/Graphics.hpp>
#include <iostream>
using namespace std;
using namespace sf;
Vector2f mapcords(int tt,int corner);
Vector2f mapcords(int tt,int corner)

if(tt ==0)
{
    if (corner ==1)
    {return Vector2f(48,8 );}
    if(corner == 1)
    {return Vector2f(48,0);}
    if (corner ==2)
    {return Vector2f(56, 0);}
    if (corner == 3)
    {return sf::Vector2f(56, 8);}

}
else{
    if(corner ==0)
    {return Vector2f(0,8 );}
    if(corner == 1)
    {return Vector2f(0,0);}
    if (corner ==2)
    {return Vector2f(8, 0);}
    if (corner == 3)
    {return sf::Vector2f(8, 8);}

}
return Vector2f(0,0 );
}

        tiletex.setRepeated(true);

            return false;

What compiler are you using? Does it tell you what line the error occurred on? The error message is not related to the tt array becuse that is an array, not a vector.

I will bet on runtime error. Something like array overflowed or Segfault.

Like the Dragon said. post your error.
