How can I fix this segmentation fault in my C code?

Segmentation faults often occur due to accessing invalid memory. Can you share the code snippet that's causing the issue?

Sure, here it is:

int main() {
    int *ptr = NULL;
    *ptr = 10; // This line causes the segmentation fault
    return 0;
}

The issue is that you're trying to dereference a NULL pointer. You need to allocate memory for ptr before using it. You can do this with ptr = malloc(sizeof(int));.

Got it! I'll add that. What should I do if I still get errors?

If you still encounter errors, check for other potential issues like uninitialized variables or buffer overflows. Feel free to share any new error messages!
