Write a C++ program which will prompt a user to enter a test score, which may be a floating point number. It should print out the following outputs, depending on the user input:

[18 Points]

Output Input Range

"Invalid score" <0

"Invalid input" non-numeric value

F 0 <= input < 60

D 60<= input < 70

C 70<= input < 80

B 80<= input < 90

A 90<= input <100

A+ 100

The screen dialog should look something like (where user input is shown in underlined italics):

Test Grading Program.

Enter a numeric score: 50.5

The grade for a 50.5 is F.
