有兩個地方錯誤：

?#include<stdio.h>
int?main()
{
	int?a[]={1,5,2,6,3,7,9,8,0};
	int?i,j,temp;
	for(i=7;i>=0;i--)
	{
	??for(j=0;j<=i;j++)
	??{
	????if(a[j]>a[j+1])
	????{	
	????	//?替換錯誤?
	????????//?temp=a[j+1];
	????????//?a[j]=temp;
	????????//?a[j+1]=a[j];
	????????temp?=?a[j];
	????????a[j]?=?a[j+1];
	????????a[j+1]?=?temp;
	????}
	??}
	}
	
	//?長度錯誤?
