void average()
{

it doesn't give me the right values for answers. It gives me 0's for answers, instead. Could you please look at each function and tell me what's wrong with them?

Thanks for the help,

Explanation / Answer

please rate - thanks

it wasn't clear if you wanted globals or parameters, so I made it all parameters

#include<iostream>
using namespace std;

//Function prototypes
void ascending(double[], int&,double&);
void descending(double[], int);
void highest(double[], int);
void lowest(double[], int);
void average(double,int);

//Global Variables


int main()
{double scores[150];
int count = 0;
int NUM_SCORES=0;
double total = 0;


cout<<"THIS PROGRAM WILL READ AT MOST 150 SCORES. THEN IT WILL"<<endl;
cout<<"PRINT THE LIST OF SCORES, THE SCORES FROM LOWEST TO HIGHEST,"<<endl;
cout<<"THE SCORES FROM HIGHEST TO LOWEST, THE HIGHEST SCORE, THE LOWEST SCORE"<<endl;
cout<<"AND THE AVERAGE OF THE SCORES."<<endl;
cout<<"--------------------------------------------------------------------------------"<<endl;



//Ascending Order
ascending(scores, NUM_SCORES,total);

//Descending Order
descending(scores, NUM_SCORES);

//Highest
highest(scores, NUM_SCORES);

//Lowest
lowest(scores, NUM_SCORES);

//Average
average(total,NUM_SCORES);
system("pause");
return 0;

}
