I need help with this code in C: $1$ Description

Consider any positive integer S$0.$ Let S$1$ be the sum of the square of its digits. Similarly, S$2$ is defined

as the sum of the squares of the digits of S$1$ and so on$.$ If Si $=1,$ for any i $>=1,$ then the initial number $($S$0)$ is said to be

a happy number. A number that is not happy is called an unhappy number. Take S$0=7,$ for example. We then have: $7->49->97->$

$130->10->1.$ This means that $7$ is a happy number. The number $4,$ on the other hand, is unhappy, since: $4->16->37->58->89->145->42->20->4.$

This sequence will obviously never lead to obtaining the value $1,$ which is necessary for a happy number $($look how unhappy it is$).$

You may have guessed that already $($right$?).$ You'll have to write a program to check whether the given numbers are happy!

$2$ Input

Input will be made from the keyboard and will consist of several input cases. The first line of the input will specify the number

of inputs to be processed, each of which is shown on a subsequent line. You can assume

that the numbers provided as input $($each number provided as input will be an S$0$ value$)$ will be less than $109$

$.$

$3$ Output

You must determine whether each of the numbers provided as input is happy or unhappy by printing one of the following messages, according to what you determine about the number:

$-$ Input #p: n is a happy number.

$-$ Input #p: n is an unhappy number.

Where p is the input number $($starting at $1)$ and n is the number originally supplied.

$4$ Input example

$3$

$7$

$4$

$13$

$5$ Sample Output

Input #$1$: $7$ is a happy number.

Input #$2$: $4$ is an unhappy number.

Input #$3$: $13$ is a happy number.

and the outputs need to be exactly the same of the sample but of course the numbers wont be the same so just the phrase
