In C$++$ Write all your code for the following steps in one file as one program. This program doesnt really do anything except illustrates various ways to use a while loop. Each of the items below are independent of each other they are not steps to accomplishing one program$\mathrm{.}1.$ Ask the user to enter a single string. Ask the user to enter an integer value for a variable called$$repetitions$.$ Use a while loop to display this$$string $($of your choice$)$ repeated repetitions times, one string per line.$$Hint: declare an integer called counter, initialized to zero$\mathrm{.}2.$ Use a while loop to count and display all the integers$$from $1$ to $20.$ Separate numbers with a space$3.$ Ask the user to enter a number larger than $100.$ Then, use a while loop to display all numbers divisible by $10$ starting from the number entered by the user all the way down to $0.$ Only show numbers divisible by $10.$ Separate numbers with a tab. TAB character is displayed using the $\backslash$t escape sequence. $($Remember that

is a newline; use similarly$)\mathrm{.}4.$ Use a while loop to keep asking the user for an integer as long as positive numbers are being entered. For every positive number entered, show its value multiplied by $2.$ Once a negative number is entered stop asking and quit the loop$5.$ Use a while loop to keep asking for a string until a particular string is entered $($for example, bye$).$Hint: declare at least two string variables.
