How to locate the highest value in a randomly filled two-dimensional array

I am making a program that inserts a two-dimensional array with random integers and locates the highest value to display it and its coordinates in the array.

I am using three files:

• utils.h
• utils.cpp
• main.cpp.

#include "utils.h"

void fillTable(int table[ROW_COL_SIZE][ROW_COL_SIZE]) {
    for(int i = 0; i < ROW_COL_SIZE; i++) { 
        for(int c = 0; c < ROW_COL_SIZE; c++) { 
            cout << rand() % table[i][c];
        }
    }
} 

void findLargest(int table[ROW_COL_SIZE][ROW_COL_SIZE], int& largestRow, 
                 int& largestCol) {
    largestRow = 0;
    largestCol = 0;

    for ( int i = 0; i < ROW_COL_SIZE; i++) {
        for ( int j = 0; j < ROW_COL_SIZE; j++) {
            if(table[i][j] > table[largestRow][largestCol]) {
                largestRow = i;
                largestCol = j;
            }
        }
    }
}

void displayTable(int table[ROW_COL_SIZE][ROW_COL_SIZE]) {
    for (int i = 0; i < 10; i++) {
        for ( int j = 0; j < 10; j++) {
            cout << table[i][j];
        }
    }
}

My program displays an array, but it is not correct:

The only thing I can change is utils.cpp.

Should fillTable fill table? Currently it does not - it only prints to cout. Therefore, table appears to remain uninitialized.

So, in fillTable, instead of:

cout << rand() % table[i][c];

You probably want something like:

table[i][c] = rand();
