Thread: C++ program in need of help!?

I am supposed to use arrays to create a program that removes the lowest number and highest number. Than it needs to add the rest but I can't even get my program to run.
The user needs to enter 8 scores:9.2,9.3,9.0,9.9,9.5,9.5,9.6,9.8.
the output should be:
contestant recieves: 56.90
Dropped low score: 9.00
Dropped High Score: 9.90


Any help to fix these errors will be appreciated. I'm not good at C++.

Code:

You should definitely revise function declaration, definition, and usage. Also, proper code formatting.

My new code. still doesn't work

Code:

#include<iostream>
#include<cmath>
#include<conio.h>
#include<iomanip> //needed for setw()
using namespace std;
// Function prototypes
int getlow(int[],int);
int gethigh(int[],int);
double getsum(int[],int);
void getinput(int[],int);
void showoutput(int[],int);
int main()
{
    int getlow,gethigh, numbers[SIZE];
    double getsum,scores,num,sum,counter,score;
void getinput(int[],int);
int getlow(int[],int);
int gethigh(int[],int);
double getsum(int[],int);
void showoutput(int[],int);
    
}
void getinput(int[],int)
{
     
cout << "Enter number of Judges Scores:";
cin >> num;
while (counter <= num )
{   
  cout << "Enter Judges Score #" <<counter << ":";
  cin >> score;
  sum+=score;
  counter++;
}
}
int getlow(int[],int limit)
{
    int  count;
    int lowest;
    
    lowest = numbers[0];
    for (count = 1; count < SIZE; count++)
    {
        if (numbers[count]<lowest)
           lowest = numbers[count];
}
    
    
int gethigh(int[],int)
{
    int count;
    int highest;
    
    highest=numbers[0];
    for(count=1;count<SIZE;count++)
{
    if(numbers[count]> highest)
    highest=numbers[count];
}
double getsum(int[],int)
{
       double scores;
       
       scores+=score
       scores-=lowest
       scores-=highest
}
void output(int[],int)
{
     cout<<setprecision(1)<<fixed<<showpoint;
     cout<<"Contestant Receives: "<<scores<<endl;
     cout<<"Dropped Low Score: "<<lowest<<endl;
     cout<<"Dropped High Score: "<<highest<<endl;
system("pause");
}

Okay, first of all, "doesn't work" is not even close to an error description.

Second of all: What are you doing inside main()? Take a close look at how you're trying to call your functions and compare that to your textbook / lecture script / whatever.

Thirdly, you are not exchanging any data between your functions. Whatever they do, it will be lost after they finish working.

IMO, indentation is roughly ok, except it's not consistent; however, missing spaces between the different blocks seems worse to me.

Yet another cross-poster.

Oh, and your compiler might wonder what "SIZE" is meant to be.

Least "she" seems to also get "cross-posting answers".

It would be more helpful if you linked to a tutorial? - Just putting people down for not following YOUR rules does not help. Ironically, your English is appalling.

Easy guys! I just wanted to make clear how hard it is for us to try and help if the code sample given is so difficult to read (which it is if all the blocks are put next to each other without any spacing). Surely I didn't want to start a fight over coding style best practices!

Is is bad to cross-post? I just want to get as much input as I can to better my knowledge in C++.
