Segmentation Fault from class function

I have a function "printWorld" in a class that prints a 2D array called "world". Whenever I use this function and run my program in the terminal it appears to print the array but then a massive amount of random numbers and at the end says "Segmentation Fault" and closes my program. As soon as I take this function out of my code though everything works just fine.

void printWorld()
{
    for(int r = 0; r <= (2*WORLD_SIZE + 1); r++)
    {
        for(int c = 0; r <= (2*WORLD_SIZE + 1); c++)
            cout << world[r][c];
        cout << endl;
    }
}

This is how the function is written in the class

game.printWorld();

This is how I'm calling the function.

This is what is showing in termninal

If it helps I have this array initialized all to 0.

As others have already stated, the mistake is the inner for loop where you compare 'r <= (2*WORLD_SIZE + 1)'

This causes an infinite loop.

Change the inner for loop to be:

    for(int c = 0; c <= (2*WORLD_SIZE + 1); c++)
        cout << world[r][c];
    cout << endl;

That should do it for you : )
