C++ array with random counts

I am stuck somewhere(have some problem with the random number) and I know it, but can't find where to fix...

Two void functions must be used; void randomNumbers(int numbers[][3], int rowSize), void randomCounts(int numbers[][3], int size, int counts[])

I can't put images to show how it should and does look like in .exe files as I just signed up today ...... Hope this works ;(

Expected Result:

//========================
//     7      6      5
//     2      1      1
//     6      7      2
//     9      3      3
//     8      1      1
//========================

//Ran. Number:       0    1    2    3    4    5    6    7    8    9
//Frequency(Counts): 0    4    2    2    0    1    2    2    1    1

What I DID:

//========================
//     0      0      0
//     0      0      0
//     0      0      0
//     0      0      0
//     0      0      0
// ========================

// Ran. Number:       0    1    2    3    4    5    6    7    8    9
// Frequency(Counts): 001A148D

Code:

#include <iostream>
#include <iomanip>
#include <ctime>
using namespace std;

const int COL = 3;
const int SIZE = 5;

void randomNumbers(int inumbers[][3], int rowSize) {
    int num = 0;
    for (int i = 0; i < 10; i++) {
        num = rand() % 10;
    }
}

void randomCounts(int inumbers[][3], int size, int counts[]) {
    for (int i = 0; i < 10; i++) {
        counts[i]++;
        cout << setw(5) << counts[i];
    }
}

int main(){

    int random[SIZE][COL] = {};
    srand((unsigned)time(NULL));

    cout << endl;
    cout << "==================" << endl;

    for (int i = 0; i < SIZE; i++) {
        for (int j = 0; j < COL; j++) {
            cout << setw(5) << random[i][j];
            if (j == COL - 1) {
                cout << endl;
            }
        }
    }

    cout << "==================" << endl;
    cout << endl;


    cout << "Ran. Number: " << setw(5) << "0" << setw(5) << "1" << setw(5) << "2" << setw(5) << "3" << setw(5) << "4" << setw(5) << "5" << setw(5) << "6" << setw(5) << "7" << setw(5) << "8" << setw(5) << "9" << endl;
    cout << "Frequency(Counts): " << randomCounts << endl;



    return 0;
}
