Use below code as reference$/$skeleton$.$ Try not to deviate from the windows x$86$ paradigms.

Write a program to ask the user to enter number less than $5.$ If the user enters greater than $5,$ the program will loop to ask the user to enter the number less than $5$ again until user enter the number less than $5.$ Display the number if the user enter number less than $5.$ The maximum attempts not more than $8$ times. If the user did not enter the number less than $5$ in $8$ attempts, the program will prompt $$Fail$$ at the screen.
