大侠帮我看下这段程序
#include<stdio.h>#include<windows.h>
int main()
{
int i,j=0,k=0;
printf("enter a number:");
scanf("%d",&i);
while(i!=-1)
{if(i>=j)
{j=i;
printf("enter a number:");
scanf("%d",&i);}
else if(i>=k)
{ k=i;
printf("enter a number:");
scanf("%d",&i);}
else
{printf("enter a number:");
scanf("%d",&i);}}
printf("the biggest is:%d\n",j);
printf("the bigger is:%d\n",k);
system("pause");
return 0;}
这里第二大的值为什么算不出来呢
