While loops

Write a C$++$ program that asks the user for an integer and then prints

out all its factors.

Recall that if a number $x$ is a factor of another number $y,$ when $y$ is

divided by $x$ the remainder is $0.$

Validate the input. Do not accept a negative integer.

Sample run of program:

Enter a positive integer:Invalid input! Try again:The factors of $42$ are $12236714$

Hint:

You need a variable called num to hold the input

and a variable called factor that would change in a loop

One while loop for validating num $($print "invalid input" while num is negative$)$

One while loop for printing the factors

The factor variable is initialized to $1.$

Print "The factors of $"$ "are" $($make sure to fill in the blank$)$

In the factor printing loop,

check if num is divisible by factor $($starting from $1)$

If so$,$ print the value in factor along with a space

increase factor by $1$

What should the condition of this while loop be$?$

$($factor is going to increase by $1$ until......$)$
