need help with two dimensional array

[tomnguyen103]

I want to convert the output screen vertically by using two-dimensional array.

Can anyone guide me out ?

//Reads data and displays a bar graph showing productivity for each plant.
#include <iostream>
#include <cmath>
const int NUMBER_OF_PLANTS = 4;
void input_data(int a[], int last_plant_number);
//Precondition: last_plant_number is the declared size of the array a.
//Postcondition: For plant_number = 1 through last_plant_number:
//a[plant_number− 1] equals the total production for plant number plant_number.
void scale(int a[], int size);
//Precondition: a[0] through a[size− 1] each has a nonnegative value.
//Postcondition: a[i] has been changed to the number of 1000s (rounded to
//an integer) that were originally in a[i], for all i such that 0 <= i <= size− 1.
void graph(const int asterisk_count[], int last_plant_number);
//Precondition: asterisk_count[0] through asterisk_count[last_plant_number− 1]
//have nonnegative values.
//Postcondition: A bar graph has been displayed saying that plant
//number N has produced asterisk_count[N− 1] 1000s of units, for each N such that
//1 <= N <= last_plant_number
void get_total(int& sum);
//Reads nonnegative integers from the keyboard and
//places their total in sum.
double round(double number);
//Precondition: number >= 0.
//Returns number rounded to the nearest integer.
void print_asterisks(int n);
//Prints n asterisks to the screen.
using namespace std;
int main( )
{
    int production[NUMBER_OF_PLANTS];
    cout << "This program displays a graph showing\n"
    << "production for each plant in the company.\n";
    input_data(production, NUMBER_OF_PLANTS);
    scale(production, NUMBER_OF_PLANTS);
    graph(production, NUMBER_OF_PLANTS);
    return 0;
}

     for (int plant_number = 1;plant_number <= last_plant_number; plant_number++)
     {

        << "Enter production data for plant number "
        << plant_number << endl;
        get_total(a[plant_number - 1]);
     }

     cin >> next;

     {
        sum = sum + next;
        cin >> next;
     }

     cout << "Total = " << sum << endl;
 }
void scale(int a[], int size)
{
    for (int index = 0; index < size; index++)
        a[index] = round(a[index]/1000.0);
}
//Uses cmath:
double round(double number)
{
    return static_cast<int>(floor(number + 0.5));
}
//Uses iostream:

{
    cout << "\nUnits produced in thousands of units:\n";
    for (int plant_number = 1;plant_number <= last_plant_number; plant_number++)
    {
        cout << "Plant #" << plant_number << " ";
        print_asterisks(asterisk_count[plant_number - 1]);
        cout << endl;

anyone helps me, plz

this is what i did so far, and i got stuck in the array in the graph function.
Can anyone help me out ?
