Write a function in C, performOperation which takes a reference to a function, which itself takes two integer inputs, and two int variables and returns the result of applying the function on the inputs. Write a function add which takes two int variables and returns the sum and another function, subtract which takes two int variables and returns the difference.

In main, you should have something like the following:

int main() {

int result1 = performOperation(&add, 5, 3);

int result2 = performOperation(&subtract, 5, 3);

printf("Result 1: %d ", result1);

printf("Result 2: %d ", result2);

return 0;

}
