Script $3$: Application Process Control

Create a C$-$Shell script program that will demonstrate the use of using sequential, conditional, and iteration to contr application process control. In your script program, please do the following:

Put $"$#$!/$bin$/$csh$"$ in the first line $($interpreter line$)$ of the program

Declare an integer variable to hold user input.

To begin sequentially, output to the screen prompting the user to enter a number.

Accept the user input, and assign it to the integer variable that you declared.

Create an if condition statement checking the number that was input to see if it is less than $100.$

If the number is less than $100,$ output to the screen that the number is less than $100.$

If the number is equal to $100,$ output to the screen that the number is equal to $100.$

If the number is greater than $100,$ output to the screen that the number is greater than $100.$

Create a while loop to reduce the variable value that the user input to $0,$ and in each iteration output to the screen th the variable. Be creative and output anything else that you would like here. Once the while loop is complete and prior of your program, output to the screen that the script has ended and goodbye.

Exit the script.

Please submit your assignment.
