 先輸出元素個數n，，，分別輸出n個元素

#include <stdio.h>void f(int a[],int n){    int i,t;    for (i=0; i<n/2;i++)    {    t=a[i]; a[i]=a[n-1-i]; a[n-1-i]=t; }}int main(){    int a[200],n,i,x;    while(scanf("%d",&n)!=EOF)    {    for (i=0; i<n; i++)  scanf("%d",&a[i]);        f(a,n);        for (i=0; i<n-1; i++)  printf("%d ",a[i]);        printf("%d\n",a[n-1]);      }}
