How to pass char array to other function c++ [on hold]

Im doing a school c++ assignment and can't seem to pass an array to another function. Here is my source code. How do I pass the arrays to the displayinfo function?

#include<iostream>
#include<array>
#include<iomanip>
#include<string>
using namespace std;

void setCourseName(string);
void InputValue();


int main()
{
    InputValue();    
}

void InputValue()
{
    char semester;
    string courseTitle;
    string courseType;
    int credits;
    string lettergrade;
    double gpa;

    array<char, 7> sem1array;
    array<string, 7> sem1coursetitles;
    array<string, 7> sem1courseTypes;
    array<int, 7> sem1credits;
    array<string, 7> sem1lettergrades;


    for (int counter = 0; counter < sem1array.size(); counter++)
    {
        bool valid1 = false;
        bool validCredits = false;
        bool valid3 = false;
        bool valid4 = false;
        while (valid1 == false)
        {
            cout << "Enter Semester Number" << endl;
            cin >> semester;
            if (semester == '1' || semester == '2')
            {
                cout << "valid input" << endl;
                sem1array[counter] = semester;
                valid1 = true;
            }
            else
