终端错误MacOS:/Applications/Xcode.app/Contents/Developer/Toolchains/xcodefault.xctoolchain/usr/include/c++/v1/istream:1634:1：注意： 当我尝试运行C++程序时，会产生错误： #include <iostream> #include <ctime> //standard c++ library of time.h using namespace std; class DateCplusplus{ private: int _day, _month, _year; //define variable public: void readValues(){ cout<<"Enter the day value: "; cin>>_day; cout<<"\nEnter the month value: "; cin>>_month; cout>>_year; _year = _year - 1900; } int verifyValues(){ if(_day>=1 && _day <=31 && _month>=1 && _month<= 12){ return 1; } return 0; } int compareValues(){ time_t now = time(0); tm *ltm = localtime(&now); if((_year == ltm -> tm_year) && (_month ==1 +ltm -> tm_mon) && (_day == ltm -> tm_mday)){ return 1; } return 0; } int main(){ DateCplusplus date; date.readValues(); cout<<"\nVerification of day and months values: "<<date.verifyValues()<<"\n"; cout<<"\nComparision of the day, the month and the year with the System current Date: "<<date.compareValues(); return 0; } };

终端中显示的错误为： /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/istream:1634:1：注意： 已忽略候选模板：无法将“基本”istream与“基本”ostream匹配 运算符>>基本\u istream&\uuuu is，位集&\uuux

你能帮我找到我的错误吗

谢谢大家!

您的主函数不能包含任何类，因此我从类DateCplusplus中提取了主函数，您的语法错误为cou>>\u年，它必须是cout

#define _CRT_SECURE_NO_WARNINGS


#include <iostream>

        cout << "\nEnter the month value: ";
