Problem 1. Create two dynamically allocated string (say Michael and Madeline) in the heap (you can malloc or use strdup) using the following pointers

char* friend1

char* friend2

Now exchange the strings using generic swap function. Also explain the output of the following function call of the generic swap

swap(friend1, friend2, sizeof(char*));

swap(&friend1, friend2, sizeof(char*));

swap(friend1, &friend2, sizeof(char*));
