Duplicate symbols for architecture?

[lmg275]

I have an assignment where I am supposed to create a header file, a function.cpp file, and a main.cpp to create a gradebook for students where you can set and adjust data using vectors of objects. My code has no syntactical errors, but it is not running. My error message is:

"linker command failed with exit code 1 (use -v to see invocation)
13 duplicate symbols for architecture x86_64"

This is my first time posting so sorry about formatting issues. Thank you in advance...

One problem is that you have names in your class with the same name as the parameters.

Student::Student(string name, char gender, int math_score, int programming_score){
newName = name;
newGender = gender;
newMath = math_score;
newProg = programming_score;
}

It's common practice to start the variable names in a class with m_
