输入年份和月份，求该月有多少天

直接上代码

#include<stdio.h>
int main(){
	int year,mounth,days;
    int mounthData[]={31,28,31,30,31,30,31,31,30,31,30,31};
	printf("input year,mounth\n");
	scanf("%d,%d",&year,&mounth);
    if(mounth<1||mounth>12)
    {
        printf("输入的月份错误");
        return 0;
    }
    if(mounth!=2)
        return mounthData[mounth-1];
	else if((year%4==0)&&(year%100!=0)||(year%400==0)) 
		//判断是否是闰年 能被4整除不能被100整除，能被400整除的年份位闰年 
		days=29;
	else
		days=28;
	printf("该月份共有：%d天",days);
}

结果
