#include using namespace std; void swap (string * first, string * last); int main () { string first, last; cout > first; cout > last; swap (&first, &last); cout << "Swapping your first and last name." << endl; cout << "Your first name is now " << first << "." << endl; cout << "Your last name is now " << last << "." << endl; return 0; } void swap (string * pfirst, string * plast) { string temp = *pfirst; *pfirst = *plast; *plast = temp; }

To be precise I forgot to add: // above swap (&first, &last) cout << "Your name is " << first << ", " << last << endl; // replace above return 0; cout << Your name is now " << first << ", " << last << endl; You don't have to pass by reference, you could have just used the swap function to reverse the order of the first and last name, but this is more impressive for an interview!

You can do it inplace my swapping the last and first char and then shifting the start index and rest string by one place each time.
