Is it possible to swap C functions?

Question

Looking to see if anyone knows if its possible to swap C functions...?

 void swap2(int(*a)(int), int(*b)(int)) {
   int(*temp)(int) = a;
   *a = *b;
   *b =          


        

Answer 1

Yes,you can. Think that a function-pointer is just a memory-address,the single requeriment is: where you will keep such address needs to be mutable. Say,int (*foo)() not really to where foo points to. May be to printf() or fopen().
