The Decrement Operator, Postfix and Prefix

Easy

Read an integer n and run two experiments that show the difference between postfix and prefix decrement. Print start: x = 5 with the value of n. Then set x to n, assign y = x--, and print after y = x--: y = 5, x = 4. Then set x back to n, assign y = --x, and print after y = --x: y = 4, x = 4. Each assignment must use the decrement operator itself, not - 1. If n cannot be read, print invalid input and return 1. If n is INT_MIN, decrementing it would overflow, so print n is too small to decrement and return 1.
