数组最好能的大点..小心越界错误....

#include <iostream>
using namespace std;

void insert(int* b,int* e,int x)
{
    if(b==e) *b=x;
    else {
        if(x<*b)swap(x,*b);
        insert(b+1,e,x);
    }
}

int main()
{
    int a[100]={12,16,19,23,26,29,36,39,45,49};
    int n=10,x;
    for(int i=0;i<n;i++){
        printf("%d ",a[i]);
    }
    printf("\n");
    while(scanf("%d",&x)!=EOF){
        insert(a,a+n++,x);
        for(int i=0;i<n;i++){
            printf("%d ",a[i]);
        }
        printf("\n");
    }    
}
