C 语言程序设计实践 5.6 好吃的苹果

AC代码：

#include <stdio.h>  
int main()  
{  
    int n,i,j,a[100]={0},t;  
    scanf("%d",&n);  
    for (i=0;i<n;i++)  
        scanf("%d",&a[i]);  
    for (j=0;j<n-1;j++)  
        for (i=0;i<n-1-j;i++)  
            if (a[i]>a[i+1]){  
                t=a[i];  
                a[i]=a[i+1];  
                a[i+1]=t;  
            }  
    printf("%d %d\n",a[n-1],a[n-2]);  
    return 0;  
}
