干才的结贴了没人看了。。。结贴太快了
我修改了下 输入后就出现错误了
#include<stdio.h>
main()
{
    int run(int year);
    int year,moth,day, i,k;
    int b,r;
    int a[12]={31,29,31,30,31,30,31,30,31,30,31,30};
    int d[12]={31,30,31,30,31,30,31,30,31,30,31,30};
    int c[12];
    printf("input year ,moth and day");
    scanf("%d%d%d",&year,&moth,&day);
    k=run(year);
    if(k==0)
    {
        for(i=0;i<12;i++)
        c[i]=a[i];
    }
    else
    {
        for(i=0;i<12;i++)
        c[i]=d[i];
    }
    for(i=0;i<moth;i++)
    b+=c[i];
    r=b+day;
    printf("pass %d days",r);
}
int run(int year)
{
    int *k;
    if((year%4==0||year%100!=0)&&year%400==0) *k=0;
    else *k=1;
    return(*k);
}
这是什么错误，谢谢

 帮你修改了一下

谢谢楼上们
