Hello, I need help with these questions.

File: Screen capture of the output screen.

1. Using a "do-while loop. the user is prompted to enter an integer value between 0 to 10 that represents it. If the entered value is outside the range 0-100, the program will force the user to re-enter the proper value before it will

continue.

2. If the entered integer value is the allowed range the value is then passed to a user-defined function that will determine the letter grade. The user-defined function will return the grade (character) to main[] AND main [] will display the character user.

Marks: letter grade:

0 to 49	F
50 to 59	D
60 to 69	C
70 to 79 80 to 100	B A
