Date and time in C ++

If on pure C ++ and on Windows, this is done through the time function with the subsequent conversion of the result into the tm structure by the localtime function. The tm structure contains the required field:

struct tm { int tm_sec; int tm_min; int tm_hour; int tm_mday; ///< то что требуется int tm_mon; int tm_year; int tm_wday; int tm_yday; int tm_isdst; }; 

Use the SYSTEMTIME structure paired with the GetSystemTime() function:

 #include <windows.h> #include <iostream> void main() { SYSTEMTIME st; GetSystemTime(&st); std::cout << st.wDay; // Вывод дня месяца } 

  #include <atltime.h> 

///////// Some code

  int Month=CTime::GetMonth(); 

Like that...

 SYSTEMTIME st; GetSystemTime(&st); cout << to_string(st.wMinute) + "-" + to_string(st.wHour) + "." + to_string(st.wDay) + "." + to_string(st.wMonth) + "." + to_string(st.wYear) << endl;
