Real quick!!! Output prob.

Hey guys I need my program to write the sorted array into an output file in addition to printing it. It prints just fine but it returns an empty output file. What am I missing? I know this is gonna be dumb/easy but Im not seeing it.

Code:

---

#include<stdio.h>
#define MAX 10

void sort(int a[], int n);

int main()
{
        int n;
        int list = 0;
        int i = 0;
        int a[MAX];

        FILE *outfile;

        outfile = fopen("output_lab3.txt", "w");

        for (i = 0; i < MAX; i++)
        {
                printf("Enter Input Number:  ");
                scanf("%d", &a[i]);
        }
        sort(a, sizeof(a) / sizeof(int));
        list = 0;
        while(list < sizeof(a) / sizeof(a[0]))
        {
                printf("%d", a[list++]);
                fprintf(outfile, "\n", a[list++]);
        }
        printf("\n");
        return 0;

        fclose(outfile);
}

int sort(int a[], int n)
{
        int x, pass, tmp, swch;
        pass = 0;
        x = 0;
        swch = 1;
        while(swch)
        {
                swch = 0;
                x = 1;
                while(x < n - pass)
                {
                        if(a[x - 1] > a[x])
                        {
                                swch = 1;
                                tmp = a[x-1];
                                a[x-1] = a[x];
                                a[x] = tmp;
                        }
                        x++;

                }
                pass++;
        }
}

You are just putting a newline character in the file. You forgot the %d format specifier.

That worked but now it prints half my numbers in the out file and half in the terminal?

That's because you have list++ for both. It increments list once when you print, and then again when you write to the file.

I dont understand what I would put as the returning value inside of a[] for the second one though?

There should only be one list++ anywhere in that output for loop. Figure out where it needs to be.

Alright guys I got it. Thanks a ton for the help.
