1) Write Single-line comments for each code in programming C++

2) Prompt the user to enter a number from 1 to 100, inclusive. If the number is not valid, meaning out of range, then indicate that the number is not valid and that they should try again. This program should test for negative numbers, which are not valid. Prompt the user to indicate that the number must be greater than 0 and that they should try again. If the number is greater than 100, then indicate that the number must be equal to or less than 100. If the number valid, then indicate to the user that the number is valid.
