help with my bubble sorting of arrays
Hi, I really need help with my bubble sorting code, i know the bubble sort is not a good one but i'm a beginner to this.
if anyone can get the code to actually sort the code or at least tell me how to change the code so it works, it's my assignment which has to be next week sometime.. help
#include<stdio.h>

while ((down <=0) || (down > 100000))
{

scanf("%d",&down);
