Answer 1

那个“\”要用一个字符变量来接收

#include <stdio.h>

int main()
{
    int year, month;
    char ch;
    int months[13] = {0, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};
    scanf("%d%c%d", &year, &ch, &month);
    if(((year % 4 == 0 && year % 100 !=0) || (year % 400 == 0)) && month == 2)
        printf("%d", months[month]+1);
    else
        printf("%d", months[month]);
    return 0;
}
