Answer 1

自己调一下吧

#include <stdio.h>
#include <stdlib.h>

unsigned int day[12] = {31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};
int main( )
{
    int year,month;
    printf("请输入年份：\n");
    scanf("%d", &year);
    printf("请输入月份：\n");
    scanf("%d",&month);

    if (((year % 4 == 0) && (year % 100 != 0)) ||
        (year%400 == 0)) {
        day[1] += 1;
    }

    printf("%d年%d月共有%d天\n",year,month,day[month-1]);

    system("pause");
    return 0;
}
