C++ - How to fill a matrix in a function and pass it to Main?

Question

C++ / C#

I know it's a simple question, but I haven't found an answer to it yet. The bottom line is to create a matrix, for example, 5x4 and fill it in a function, and then pass the result back to Main so that you can then pass it to other functions. Or is it done somehow easier and I complicate everything?

Answer 1

You need to create a matrix, pass it to the function, fill it and return it to main.
For a matrix, either create a class, or do int m[5][4] .

Thanks to maaGames for the advice. If anyone is interested, here is the code itself:

#include "stdafx.h"
#include <iostream>
#include <ctime>

using namespace std;

int FillMatrix(int Mat[5][4])
{
  for (int i = 0; i < 5; i++)
  {
    for (int j = 0; j < 4; j++)
    {
      Mat[i][j] = rand() % 50;
    }
  }
  return Mat[5][4];
}

int main()
{
  srand(time(0));
  int Matrix[5][4];

  FillMatrix(Matrix);
  for (int i = 0; i < 5; i++)
  {
    for (int j = 0; j < 4; j++)
    {
      cout << Matrix[i][j] << "\t";
    }
    cout << endl;
  }

  system("pause");
    return 0;
}
