errors are

It looked like you had two extra }'s. You're also using a while statement with nothing..

I suggest you go read this: http://www.learncpp....ile-statements/

P.S. I'm not the best with C++ but I think this may be it.

[Glenda Ruth Hayes]

it does have a statement. idk what it could be looks like im going to fail it oh well i will talk to my teacher

[Nathan]

void sortArray(float,int);

Try using:

void sortArray(float [],int);

Hey man,

Don't know if this is what you looking for, I have reviewed your code and just fixed things up abit as not to produce any errors. Even if it's not ,maybe you can adjust it making it do what you want. I have left comments next to all the code I have changed that caused error and given it a very basic description of why it should be like it is. Hopefully it'll also help make you realize where it is you went wrong and fix it in any later versions.

Edit: Also changed your GPA to an array where ever necessary

#include <iostream>
#include <fstream>
#include <cstdlib> // You were missing this library (need for using "system()")

using namespace std;

//this program is going to output the student id and gpa in accending order
//function prototype
void sortArray(float[],int);

int main()
{
    const int SIZE= 3; //Array size
    int id[SIZE];
    float GPA[SIZE]; // Need to make an array since you sending through an array in your sortArry function, it must also be a float type to match the function header
    int j;

    ifstream inputFile;
    char dataFile[20];

    inputFile.open("dataFile.txt");

    char fileName[20];
    cout<<" The file name is GPA.txt";
    ofstream outputFile;
    outputFile.open("GPA.txt");
    cout<<id<<endl;
    cout<<GPA<<endl;

    for(j = 0; j< SIZE; j++)
    {
        cout<<"please enter the student id number"<<endl;
        cin>>id[j];
        cout<<"please enter the gpa. "<<endl;

        while(GPA[j]!=SIZE - 1) // Should set this or it'll cotinue until your old specified 99
        {
            cout<<"please enter the gpa. ";
            cin>> GPA[j]; // Must store it some where in the array of GPA
            cout<<GPA[j];
        }

        sortArray(GPA, SIZE);
        inputFile.close();
        outputFile.close();
        system("pause");
        return 0;
    }
}

void sortArray (float array[],int SIZE)
{

    bool swap;
    float GPA;

    do
    {
        swap=false;
        for(int count=0; count>(SIZE-1); count++) // You have to declate count type (as integer)
        {
            if(array[SIZE]> array[SIZE + 1])
            {
                GPA=array[SIZE];
                array[SIZE]=array[SIZE + 1];
                array[SIZE + 1] = GPA;
                swap = true;
            }
        }
    }
    while (swap);

    cout<<GPA<<endl;
}

Peace Out

thanks on the array size thats what my teacher told me to put it as. so it has to be 100 lol and i had to set it to stop at 99.9 that was teh sentail value. lol but everything else makes since. lol i knew it was something that i kept over looking. to bad i got a zero on it now. lol for it not compiling that day
