Segmentation faults occur when a program tries to access memory it shouldn’t. To prevent them, follow these methods:
1. Initialize pointers: Uninitialized pointers can cause segmentation faults. Always initialize your pointers before use.
2. Check for null pointers: Before dereferencing a pointer, ensure it’s not null.
3. Stay within array bounds: Overstepping the boundaries of an array is a common cause of segmentation faults. Always check that you’re within the array size.
4. Freeing memory: Be careful when freeing memory. Don’t free the same memory twice and don’t use memory after it has been freed.
5. Use tools: Utilize debugging tools like Valgrind or GDB to detect potential issues causing segmentation faults.
