Programming Projects Write a program that asks the user to enter a two-digit number, then prints the number with its digits reversed. A session with the program should have the following appearance: Enter a two-digit number: 28 The reversal is: 82 Read the number using %d, then break it into two digits. Hint: If n is an integer, then n % 10 is the last digi in n and n 10 is n with the last digit removed. Extend the program in Programming Project l to handle three-digit numbers. 1. 2, 3. Rewrite the program in Programming Project 2 so hat it prints the reversal of a three-digit gram of Scction 4. upc.c /*Computes a Universal Product Code check digit / #include int main (void) first sum, second sum, total; printf ("Enter the first (single) digit: ") scanf ( " % ld", &d) ; printf ("Enter first group of five digits: " scanf ( " % ld%ld%ld% ld%ld". &il, &i2, &13, &14 , &i5); printf ("Enter second group of five digits: ") The missing check digits are 8 (Jif) and 6 (0cein Spray).
