$4\mathrm{.}4\mathrm{.}1$: While loop: Print $1$ to N$.$

Write a while loop that prints from $1$ to user$\_$num, increasing by $1$ each time.

Write a program that lets a user enter N and that outputs N$!($N factorial, meaning N$*($N$-1)*($N$-2)*...*2*1).$ Hint:Use a loop variable i that counts from total$-1$ down to $1.$ Compare your output with some of these answers: $1$:$1,2$:$2,3$:$6,4$:$24,5$:$120,8$:$40320.$

Write a program that prints the U$.$S$.$ presidential election years from $1792$ to present day, knowing that such elections occur every $4$ years.

Given positive integer num$\_$insects, write a while loop that prints, then doubles, num$\_$insects each iteration. Print values $100.$ Follow each number with a space.

$4\mathrm{.}3\mathrm{.}3$: While loop: Insect growth.

Given positive integer num$\_$insects, write a while loop that prints, then doubles, num$\_$insects each iteration. Print values $100.$ Follow each number with a space.

Write an expression that continues to bid until the user enters $\text{'}$n$\text{'}.$

Sample output with inputs: $\text{'}$y$\text{'}\text{'}$y$\text{'}\text{'}$n$\text{'}$

Write a while loop that prints user$\_$num divided by $2$ until user$\_$num is less than $1.$ The value of user$\_$num changes inside of the loop.

Write a while loop that prints user$\_$num divided by $2$ until user$\_$num is less than $1.$ The value of user$\_$num changes inside of the loop.

Write an expression that executes the loop body as long as the user enters a non$-$negative number.
