The variables xp and yp have both been declared as pointers to integers, and have been assigned values. Write the code to exchange the two integers- (so that after the swap xp still points at the same location, but it now contains the integer value originally contained in the location pointed to by yp; and vice versa-- in other words, in this exercise you are swapping the integers, not the pointers). Declare any necessary variables.

This is what I tried:

int temp = *xp; xp = yp; yp = *temp;
