This program will determine if the number entered by the user is happy or not happy. This process involves computing the sum of the squares of the digits of a number. If the number $($n$)$ is not initially $1$ or $42,$ n is updated to be the sum of the squares of its digits. This process is then repeated until n either n reaches $1($happy$)$ or $42($not happy$).$ This process is explained further below.
