Function pointers are often used in scenarios where different functions need to be used based on runtime conditions or requirements. One common example is sorting an array of integers using a custom comparison function. By using a function pointer, the sorting algorithm can be made flexible to sort in ascending or descending order based on the provided comparison function.
