Please write a C$++$ program with $3$ functions.

$1.$ The main$()$ function gets an integer from the user using the cin C$++$ statement.

make sure it's a positive integer. If it's zero or a negative integer loop until you get a positive integer.

which loop is best to use here?

while loop?

do while loop?

for loop?

Once you have a positive integer, call a function called print$\_$evens and pass to it this integer.

$2.$ The print$\_$evens function prints all even numbers from zero to the number it was passed from main$()$

while it's printing these numbers in a loop, it will call the $3$rd function which checks to see if a number is divisible by $8.$

the $3$rd function will be called divisible$\_$by$\_8.$ It will be passed an integer and will return a boolean.

the print$\_$evens function does not return anything.

so you have main$()$ where your program starts running.

you ask the user for an integer in main$().$ Do some error checking to make sure only positive integers are accepted as input. If the user types $-5$ then you should print a message saying "Please input a positive integer" and loop back.

Then you call the print$\_$evens function and pass it this positive integer.

print$\_$evens will print all the even numbers starting from $0$ up to this positive integer.

print$\_$evens will call the $3$rd function called divisible$\_$by$\_8$ and pass it each even number and this function will return true if the number is divisible by $8$ and false if it's not.

You can have an if statement in print$\_$evens like this:

if $($divisible$\_$by$\_8)$

$//$ print that number is divisible by $8$

$\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

a sample run can look like this:

Please input a positive integer: $-5$

That wasn't a positive integer, please input a positive integer: $20$

$0$

$0$ is divisible by $8!$

$2$

$4$

$6$

$8$

$8$ is divisible by $8!$

$10$

$12$

$14$

$16$

$16$ is divisible by $8!$

$18$
