Write a program that accepts input like the program in Display 7.8and that outputs a bar graph like the one in that display exceptthat your program will output the bars vertically rather thanhorizontally. A two-dimensional array may be useful.

Thats the question and here is what Display 7.8 looks like

#include <iostream>

#include <cmath>

const int NUMBER_OF_PLANTS = 4;

void input_data(int a[], int last_plant_number);

void scale(int a[], int size);

void graph(const int asterisk_count[], int last_plant_number);

void get_total(int& sum);

int round(double number);

void print_asterisks(int n);

int main()

{

using namespace std;

int production[NUMBER_OF_PLANTS];

cout << "This program displays agraph showing\n"

<< "production foreach plant in the company.\n";

input_data(production,NUMBER_OF_PLANTS);

scale(production, NUMBER_OF_PLANTS);

graph(production, NUMBER_OF_PLANTS);

return 0;

}

void input_data(int a[], int last_plant_number)

void get_total(int& sum)

void scale(int a[], int size)

int round(double number)

void graph(const int asterisk_count[], int last_plant_number)

{

using namespace std;

cout << "\nUnits produced inthousands 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;

}

}

void print_asterisks(int n)

{

using namespace std;

for (int count = 1; count <= n;count++)

cout << "*";

}

I guess the problem is, that I cant even get this to work. I have typed it in several times and was wondering if there is something obvious I am missing.
