用C++写一个日历程序，要求输入年份，显示全年的日历

#include <iostream> #include <iomanip> #include <string> using namespace std; class Caldendar{ protected: int m_year; //年份 int m_month; //月份 static long long t_day; //计算距离公元元年的天数 int m_day[12]; //一年中每个月的天数 public: void setyear(int year); //输入年份 bool isleapyear(); //判断是否是闰年 void getdays(); //获得每月天数 void print(); //打印日历 }; long long Caldendar::t_day = 0; void Caldendar::getdays() { if(isleapyear() == true) { int day[12] = {31,29,31,30,31,30,31,31,30,31,30,31}; for(int i = 0;i < 12;i++) { m_day[i] = day[i]; } } else { int day[12] = {31,28,31,30,31,30,31,31,30,31,30,31}; for(int i = 0;i < 12;i++) { m_day[i] = day[i]; } } } void Caldendar::setyear(int year) { m_year = year; } bool Caldendar::isleapyear() { if((m_year%4 == 0&&m_year%100 != 0)||(m_year%400 == 0)) { return true; } else { return false; } } void Caldendar::print() { char *t_month[12] = {"一月（Jan）","二月（Feb）","三月（Mar）","四月（Apr）","五月（May）","六月（Jun）","七月（Jul）","八月（Aug）","九月（Sep）","十月（Oct）","十一月（Nov）","十二月（Dec）"}; char *t_week[7] = {"Sun","Mon","Tue","Wen","Thru","Fri","Sat"}; long long count = 0; //用于换行 for(int i = 1;i < m_year;i++) { if((i%4 == 0&&i%100 != 0)||(i%400 == 0)) { t_day += 366; } else{ t_day += 365; } } count = t_day%7+1; system("reset"); cout<<"年份："<<m_year<<endl; for(m_month = 0;m_month < 12;m_month++) { cout<<"---------------------------------"<<endl<<endl; cout<<t_month[m_month]<<endl; for(int m = 0;m < 7;m++) { cout<<t_week[m]<<" "; } cout<<endl; int j = 0; for(int k = 0;k < count%7;k++) { cout<<setw(3)<<" "; } for( j = 0;j < m_day[m_month];j++) { count++; cout<<setw(3)<<j+1<<" "; if(count%7 == 0) { cout<<endl; } } cout<<endl; } } int main() { int year = 0; cout<<"请输入年份:"; cin>>year; Caldendar p; p.setyear(year); p.getdays(); p.print(); return 0; }
