One Question of the Day 55

Question 55: Output an array in reverse order.
#include “stdio.h”
void main()
{ int arr[10]; int i,j; int temp;

//初始化 
printf("please input the arr:\n");
 for(i=0;i<10;i++)
     scanf("%d",&arr[i]);
 
 //运算  
 for(i=0,j=9;i<5;i++,j--)
       {
        temp=arr[i];
        arr[i]=arr[j];
        arr[j]=temp;
        }
     
 //输出： 
printf("the result is :\n");
for(i=0;i<10;i++)
     printf("%5d",arr[i]);

}
