Thread: What was wrong with this code??

I suggest you use Quzah's suggestion for debugging. printf() is a lot easier to use than GDB.

Here is an example that might be a little more pertinant to you:

Code:

int a, c, b = 10;
char array[10];
for(a = 0; a <= b; a++) {
    c = array[a];
}

The above code will probably give you a seg fault. If you add in a printf() statement like so:

Code:

int a, c, b = 10;
char array[10];
for(a = 0; a <= b; a++) {
    printf("About to access index %d\n",a);
    c = array[a];
}

You will (hopefully) get the seg fault before it prints "About to access index 10". This helps you to realize that you are accessing the array outside its bounds.
