Q5 (20 points) a) (10 points) Write a C program which inputs three numbers from the user, and outputs the message "S sorted" otherwise. orted." if the entered numbers are in ascending order, or outputs the message "Not b) (10 points) Write a C program that swaps the contents of two pointer variables to integers. That is, suppose you have two integer variables, numberl and number2; and two pointers to integers, intPtrl and intPtr2. If intPtrl pointes to numberl, and intPtr2 points to number2 before the swap takes place, then after the swap operation intPtr2 should point to numberl, and intPtrl should point to number2. Make sure that your program displays the numbers pointed to by the pointers before and after the swap operation
