Keep getting -fpermissive errors on my program

[nruiz8]

Basically, the output of my program is supposed to be like this:
The class scores are:
Students # Test#1 Test#2 Test#3
1 88 98 76
2 76 88 87
3 56 77 55
4 55 89 66
5 76 98 66
6 87 84 81
7 80 91 77
8 69 70 81
9 85 99 77
10 88 91 79

The class average for test #1 is : ?
The class average for test #2 is : ?
The class average for test #3 is : ?

The problem is that whenever I run my code I get these errors:
[Error] invalid conversion from 'int' to 'int (*)[3]' [-fpermissive]
[Error] initializing argument 1 of 'double ClassAvg(int (*)[3], int)' [-fpermissive]
[Error] invalid conversion from 'int' to 'int (*)[3]' [-fpermissive]

Your ClassAvg() function expects a two dimensional array of int for the first parameter yet you're trying to pass a single int instead. You probably mean to pass the table, not scores.

I mean, I kept the ClassAvg(table,scores) and took out some other things, and it did give me the table with the students' test scores, but idk how to show the class average scores: This is the simplified code that worked, but doesnt show the class averages:

//Compute a program that declares and initializes a two dimensional array called scores
#include<iostream>
#include<iomanip>
using namespace std;
const int testNum=3;
const int scores=10;
 double ClassAvg(int scores[10][3], int testNum);
 
 int main()
 {
 	int table[scores][testNum]={{88,98,76},
	                           {76,88,87},
							   {56,77,55},
							   {55,89,66},
							   {76,98,66},
							   {87,84,81},
							   {80,91,77},
							   {69,70,81},
							   {85,99,77},
							   {88,91,79} };
							   
 						   	
  
    cout<<"The class scores are:\n";
    
    ClassAvg(table,scores);
  	
  	return 0;
  }
   double ClassAvg(int array[][testNum], int numRows)
   {
   	 for(int row=0;row<numRows;row++)
   	 {
   	 	for(int col=0;col<testNum;col++)
   	 	{
   	 		cout<<setw(5)<<array[row][col]<<" ";
   	 	}
   	 	cout<<endl;
   	 }
   }

What exactly are you trying to average? The rows like {88, 98, 76} or the columns 88, 76, 56, 55, 76, etc?

[nruiz8]

the columns, 88,76,56,55,76, etc

[jlb]

Okay then you only need one loop to loop through the columns. The rows will be constant throughout the function. Something more like:

double ClassAvg(int array[scores][testNum], int column)
{

      for(int i = 0; i < scores; i++)  // You may want to actually pass "scores" as a parameter as well. 
      {
         cout << setw(5) << array[i][column] << " ";
      }
      cout << endl;

But instead of printing the numbers, you'd sum them, then average them and then return the average.

And you may want to start adding a little bit of whitespace in your "calculations" to make reading the code easier.
