int day,month,year,sum,leap; 为什么定义这即个都是什么意思?please input 【程序4】 输入某年某月某日,判断这一天是这一年的第几天?1.程序分析：以3月5日为例,应该先把前两个月的加起来,然后再加

帮我改改,int days=sum_day(month,day); if(leap(year)&&month>2) days++; #include int sum_day(int ,int),leap(int);void main(){int year,month,day;cout>year>>month>>day;int days=sum_day(month,day);if(leap(year)&&month>2)days++;cout ( )month( )Day( )Year 4.设int year,month,day分别表示一个日期中的年月日,试编程求 int day,month,year,sum,leap; 提示说语法错误,main(){int day,month,year,sum,leap;printf( please input year,month,day );scanf(%d,%d,%d,&year,&month,&day);switch(month)/*先计算某月以前月份的总天数*/{case 1:sum=0;break;case 2:sum New year‘s day is___(填介词）the first month of the year 这个程序错误在哪里?#include using namespace std;class Date{public:void setDate(int y,int m,int d);void showDate();private:int year;int month;int year;};void Date::setDate(int y,int m,int d){year=y;month=m;day=d;}void Date::showDate(){cout c 语言改错#include stdio.hvoid main(){int a,b,year,day,month;scanf(%d%d%d,&year,&month,&day);switch(month){case 1:month=0;break;case 2:month=31;break;case 3:month=59;break;case 4:month=90;break;case 5:month=120;break;case 6:month=151;break;ca C++:abnormal program termination //我的编译器是VC6.0#include#include#include//using namespace std;class Date{int year,month,day;void init();public:Date(const std::string& s);Date(int y=2000,int m=1,int d=1);void display(); friend ostream& opera January,month,is,the,and,we,have,Year's,New,first,Day,in,this,month 连词组句 Think of the best day(s) you have had in the past month or year英译汉 用函数计算每个月的天数,C语言问题,必须是先设计一个函数我这个哪里错了?#include #includeint main(void){ int f(int x,int y);int year ,month,day,t;printf(输入年月日：);scanf(%d%d%d,&year,&month,&day);t==f(year,mon It's the tebth month in a year.还有the month is after August.christmas day is in this month.tree-pianting day is in this month.the month is before May.
