This program is meant to call to read_in, sum_row, and print. However, I am getting error messages saying that these functions are not declared in this scope. How can I fix this? I'm sure its somewhat of an easy fix but I am just starting to learn function calls and I can't for the life of me figure this out. Any help is very much appreciated, thank you!
#include <iostream>
#include <iomanip>
using namespace std;
int sum = 0;
int row = 0;
int col = 0;
const int stud_num_rows = 28;
const int stud_num_cols = 10;
const int fac_num_rows = 15;
const int fac_num_cols = 10;
const int staff_num_rows = 100;
const int staff_num_cols = 10;
const int adm_num_rows = 30;
const int adm_num_cols = 10;
int main()
{
int students[28][10];
int faculty[15][10];
int staff[100][10];
int admin[30][10];
read_in(students, faculty, staff, admin);
sum_row(students, faculty, staff, admin);
print(students, faculty, staff, admin);
return 0;
}
void read_in(int students[][stud_num_cols],
int faculty[][fac_num_cols],
int staff[][staff_num_cols],

You have to either move other functions above main(), or put function prototypes above main().
