not going to do it for you but typically getter and setter functions are named, and have parameters, etc, that involve setting or returning the value of a class member variable.

for example

class c
{
double attendance;
double get_attendance() {return attendance;} //tiny functions are ok put here without an external body.
void set_attendance(double in) {attendance = in;}
}

not sure why all yours take something called 'grade' which seems confusing (to human readers). It would work, its just confusing.

I just want to point out that I wouldn't use #pragma, as it is not supported by all compilers, but when it isn't, it won't produce an error and your program won't work. Better is:

#ifndef SOMETHING_H
#define SOMETHING_H
//Your code

#endif //SOMETHING_H defined

If you're unsure what getters and setters are, take a quick look at google for C++ tutorials - this site has a tutorial course, in fact! There are tons of examples and explanations as to what setters and getters are.

Really all that setters are is that they take a parameter and use it to set the value of a corresponding data member in the class.
A getter returns the data member's value - it "gets" the value.
