2d Array as a function help

[Aerion4]

hey team, i need a little direction on my program. Im trying to use my 2d array in a function, and im having a hard time getting the syntax correct. when i run this, i get an error, but it says "2 external errors" and it dosent point me to any part of my code...any input or direction would be appreciated. Clearly, im a beginner, so if you could try and keep it simple, id appreciate that.

// testscore.cpp.cpp : main project file.
//three arrays: a one-dimensional array to store the students’ names,
//a (parallel) two-dimensional array to store the test scores,
//and a parallel one-dimensional array to store grades.
//Your program must contain at least the following functions:
//a function to read and store data into two arrays,
//a function to calculate the average test score and grade,
//and a function to output the results.
//Have your program also output the class average.
