阅读以下程序: #include using namespace std; class Tdate { private: int year; int month; int day; public: void setDate(int a,int b,int c); int getYear(); void print(); bool isLeapYear(); }; void Tdate::setDate(int a,int b,int c) { year=a; month=b; day=c; } int Tdate::getYear() { return this->year; } void Tdate::print() { cout< } bool Tdate::isLeapYear() { bool leapYear=false; if((year%4==0&&year%100!=0)||year%400==0) { leapYear=true; } return leapYear; } int main() { Tdate today; today.setDate(2018,6,14); today.print(); if(today.isLeapYear()==true) cout< else cout< return 0; } 上述 程序执行后的输出结果为
