Help with using math(algorithm) in C++ programming and Raptor(flowchart) (pay 10$)

I'm new to C++ and raptor and I don't really have the patience to learn C++, as soon as I finish this one, I don't have to take any programming classes. So please help.

I have to develop algorithm and describe in C++ and raptor, if you do my homework, I will pay 10$ for doing it for me. It shouldn't be hard for the pro(s)

One example:
A student’s letter grade is calculated according to the following schedule:
Numerical grade Letter grade
greater than or equal to 90 A
less than 90 but greater than or equal to 80 B
less than 80 but greater than or equal to 70 C
less than 70 but greater than or equal to 60 D
less than 60 F
