Function $1$: Begin the program by calling a "welcome" function. Use the template you created in the previous lab

This function generates an opening screen that welcomes the user and

explains $($briefly$)$ the purpose of the program and any directions you think the user needs.

Function $2$: Next, call a function that asks the user to enter a series of positive numbers.

Validate the user's input $($assure that the input is positive$).$ An error message is to be displayed if the user enters a negative number and you do not want to count it as a valid entry. $($Section $5\mathrm{.}3$ in the text reviews a very common & useful input validation technique.$)$ The program should not continue until a valid entry is entered. USE A LOOP FOR THIS.

The user will enter a zero to signal they have no more data to input. $($Make sure this is explained to the user.$)$

This function returns the number of valid entries $($the number of positive numbers entered$).$ There's multiple example programs in Revel dealing with functions that return a value $-$ review them as needed.

Function $3$: Now, call a function that accepts the number of positive numbers entered by the user $($from previous step$)$

This function will simply display a message stating one of the following:

$"10$ or fewer positive numbers were entered" or

"More than $10$ positive numbers were entered."

Display a message indicating that the program has ended.

Ensure that your program runs correctly before submitting. Submit the $.$cpp on Canvas for credit.
