Figure $2$: How digit $8$ is represented using asterisks. In this example, the length of each

horizontal segment is $16$ asterisks and the length of each vertical segment is $12$ asterisks.

print a message stating that the length is not acceptable and the user must try entering the length

again. When user enters an acceptable length for the horizontal segments, then, the program prints

out the following message on screen:

$$Now$,$ enter the length of vertical segments $($from $3$ to $40)$: $$

After the user enters the length of vertical segments using keyboard, your program will check the

entered length. If the length is less than $3$ or greater than $40,$ the program must print a message

stating that the length is not acceptable and the user must try entering the length again. Also, if

the length of vertical segment is greater than twice the length of horizontal segment or less than

half of the length of horizontal segment, the program must print a message stating that the length

is not acceptable and the user must try entering the length again. When user enters an acceptable

length for the vertical segments, then, the program prints out the following message on screen:

$$Enter a positive integer: $$

After the user enters the positive integer, the program checks to see if the user input is a valid

positive integer. If the user input is not legal, the program must print out a message stating

that the user input is not acceptable and the user must try entering the positive integer again.

When user enters an acceptable input $($a positive integer$),$ the program prints out the seven$-$segment

representation of that number. Then, the program repeats this process $($printing the message $$Enter

a positive integer: $$ and printing out its seven$-$segment representation$)$ indefinitely.

To end this infinite loop, user can simply presses Ctrl $+$ D $,$ which is a way to pass

EOF character to the program via standard input stream $($keyboard$).$
