c++

Write a program that takes a single number from the user and returns the number multiplied by the number+4. Example - the number 3 entered by the user would return 3 times 7 or 21. Example 2 - the number 5 entered by the user would return 5 times 9 or 45. Remember, you should always output to the user in textual form what is expected for keyboard entry. Make sure you have appropriate comments and output to explain the program's function. After
