}

int Multiply(int i, int j){
return i*j;
}

int main()
{
ptrInt ptr1 = Add;
ptrInt ptr2 = Multiply;

printf("%d\n", (*ptr1)(2,3)); //will print 5
printf("%d\n", (*ptr2)(2,3)); //will print 6
return 0;
}

You can also create an Array of function-pointers. If all the pointers are of the same "structure":

int (*array[2]) (int x, int y); // can hold 2 function pointers
array[0] = Add;
array[1] = Multiply;

You can learn more here and here.

It is also possible to define an array of function-pointers of different types, though that would
require casting when-ever you want to access the specific function. You can learn more here.
