获得当前时间
#include#include //time_t tm #include using namespace std; class CDateTime { private: //年 月 日 时 分 秒 int year; int month; int day; int hour; int min; int sec; public: CDateTime() { year = month = day = 1; hour = min = sec = 0; } //获得当前时间 void Now() { time_t tn; tm tmp; time(&tn); localtime_s(&tmp, &tn); year = tmp.tm_year + 1900; month = tmp.tm_mon + 1; day = tmp.tm_mday; hour = tmp.tm_hour; min = tmp.tm_min; sec = tmp.tm_sec; } void PrintDate() const { printf("year:%d,month:%d,day:%d.n", year, month, day); } }; int main() { CDateTime cd; cd.Now(); cd.PrintDate(); return 0; }
