Need a for loop to sort an array
I have an array of numbers that I read in from the user. I know that they have been read in correctly because I am able to print them. Only problem is I can't sort my array. Can someone please help?
Code:
#include <stdio.h>
#include <string.h>
int main (void)
{
char fname[256];
FILE* fin;
int n; //Size of the set allowed digits
int k; //Length of the target numbers
int numbers[10];
int i, j;
int temp;
printf("Enter the name of the file to read from: \n");
scanf("%s", fname);
fin = fopen(fname, "r");
//Check to make sure the file exists and opens correctly
if(fin == NULL)
{
printf("Unable to open the file %s\n", fname);
system("PAUSE");
return 0;
}
/*Read in the two integers on the first line of the text file*/
//How many numbers to read in
fscanf(fin, "%d ", &n);
//0 in the file means stop!
if (n == 0)
return;
//How many digits for each number to be
fscanf(fin, "%d ", &k);
//Make sure array is empty
for (i = 0; i <= n; i++)
{
numbers[i] = 0;
}
//Second line
for(j = 0; j < n; j++)
fscanf(fin, "%d \n", &numbers[j]);
//Sort the array
for (i = 0; i < n; i++)
{
for (j = i + 1; j < n; j++)
{
if (numbers[i] > numbers[j])
{
temp = numbers[i];
numbers[i] = numbers[j];
numbers [j] = temp;
printf("We are in the sort loop now \n");
printf("%d \n", numbers[i]);
}
}
}
fclose(fin);
system("PAUSE");
return 0;
}
