Question

I created a 2d array of structures and now I want to assign values to x, y, and z. Any ideas where the segmentation fault is coming from?

struct xyz
{
    int x;
    int y;
    int z;
};

char buf[80];

struct xyz array[width][height];

for(row=1;row<=width;row++)
{
    for(col=1;col<=height;col++)
    { 
        fgets(buf,80,file);
        array[row][col].x = strtol(buf, NULL, 10);
        fgets(buf,80,file);
        array[row][col].y = strtol(buf, NULL, 10);
        fgets(buf,80,file);
        array[row][col].z = strtol(buf, NULL, 10);
    }
}

SI there a reason you’re running from 1 to hight/col? In C all array begin in 0 and end in length-1.

In other word the for loops should look like:

for(row=0;row<width;row++)
{
   for(col=0;col<height;col++)
   {
