Answer is 6.
This function basically counts number of characters in a string.
The function madeeasy(int *p1) basically counts number of characters in input string..
Inside madeeasy(int *p1) pointer p2 is initialized as p1.
The statement while(*++p1) increments p1 till ‘ \ 0’ is reached! p1 is incremented by 6..
Finally the difference between p1 and p2 is returned which is 6.
