利用数组，正序输入十个数，倒序输出；利用两个程序文件
#include <stdio.h>void main()
{
void reverse(int a[],int n);
int a,i;
printf("Please input 10 numbers:");
for(i = 0;i < 10;i++)
{
scanf("%d",&a);
}
reverse(a,10);
for(i = 0;i < 10;i++)
{
printf("%d ",a);
}
}
#include <stdio.h>
void reverse(int a[],int n)
{
int temp,m,*i,*j,*p;
m = (n - 1)/2;
j = a + n - 1;
i = a;
p = a + m;
for(;i < p+1;i++,j--)
{
temp = *i;
*i = *j;
*j = temp;
}

其实反序输出只要排序号的数组尾部遍历就行
