Write a $C$ program that prompts the user to enter a positive integer $($num$)$ and then calls a function, to which

you pass the value num, and which displays the shape of a parallelogram of that size using any visible character

that you would like $($for example, ${?}^{****}).$ You can assume that the user will enter an integer, but you must check for

the cases that they enter a negative number and take some course of action to make it positive. The course of

action is up to you.

The following example output results when num $=-7,$ num $=5,$ and num $=6,$ for the three separate runs. Note

that figures are displayed across the page only to save space.
