Thread: Can't get my C++ program to run!

Hi Guys,

Tried to take on the points everyone has passed onto me and have come up with the following that:

I Been asked to create a SIMPLE program with an array that holds values from 0 - 100. I then need to write functions to calculate:

- largest number in the array
- smallest number in the array
- the sum of all of the numbers in the array
- the mean of all of the numbers in the array

So I created a file called values.h that I want to calculate (get) and show (display) the values on screen:

Code:

// values.h
// Determining the largest, smallest, sum and mean
# include <iomanip>
//# include <iostream.h>
//# include <iomanip.h>

class values
  {
   public:
     int get_largest_number();
     int get_smallest_number();
     int get_sum_of_number();
     int get_mean_of_number();
     void display_largest_number() ;
     void display_smallest_number() ;
     void display_sum_of_number() ;
     void display_mean_of_number();
   protected:
     int largest_number;
     int smallest_number;
   };

int values::get_largest_number(int a[])
{
     largest_number = a[0];
     
     for(i=1; i<20; i++)
     { 
       if(a[i] > largest_number)
       {
            largest_number = a[i];
       }
     }
} 

int values::get_smallest_number(int a[])
{
     smallest_number = a[0];
     
     for(i=1; i<20; i++)
     { 
       if(a[i] < smallest_number)
       {
            smallest_number = a[i];
       }
     }
} 


int values::get_sum_of_number(int a[])
{
     int avg;
 
     avg = get_sum_of_number(a); 
     avg /= 20; 
     return(avg); 
} 

int values::get_mean_of_number(int a[])
{
     int mean; 
     
     for(i=1; i<20; i++)
     { 
       mean += a[idx]; 
     }
     return(mean); 
} 


void values:: display_largest_number()
  {
  cout <<"The largest number is:" <<largest_number;
}

void values:: display_smallest_number()
  {
  cout <<"The smallest number is:" <<smallest_number;
}

void values:: display_sum_of_number()
  {
  cout <<"The sum of the numbers is:" <<avg;
}

void values:: display_mean_of_number()
  {
  cout <<"The mean of the numbers is:" <<mean;
}

Then get my main program to run it:

Code:

// ASSIGN77.CPP
// A Program to display the largest, smallest, sum and mean
#include "values.h"
#include <stdlib>
//#include "values.h"//
//#include <stdlib.h>//
void main ()
	{
    values arithmetic;
    arithmetic.get_largest_number ();
    arithmetic.get_smallest_number ();
    arithmetic.get_sum_of_number ();
    arithmetic.get_mean_of_number ();
    arithmetic.display_largest_number ();
    arithmetic.display_smallest_number ();
    arithmetic.display_sum_of_number ();
    arithmetic.display_mean_of_number ();
    system ("pause");
	}

...but it just wont run - any ideas please?
