C ++: Obtain the current time

I think there is a date class. Unlike Java, C ++ does not have this class, you can use the time. H function of the C library to obtain the current time, or call the DOS date

Method 1:

#include <iostream>#include <ctime>#include<string>using namespace std;int main (){  time_t rawtime;  struct tm * timeinfo;  time ( &rawtime );  timeinfo = localtime ( &rawtime );  cout<<"Current local time and date:"<< asctime (timeinfo)<<endl; system("pause");  return 0;}

Method 2:

#include<iostream>#include<ctime>#include<string>using namespace std;int main(){time_t lltime;time(lltime);cout<<"the time is "<<ctime(lltime)<<endl;system("pause");return 0;}

Method 3:

include <ctime>#include<string>using namespace std;#define CCT (+8)int main (){  time_t rawtime;  struct tm * ptm;  time ( &rawtime );  ptm = gmtime ( &rawtime );   cout<<"Beijing (China):"<<(ptm->tm_hour+CCT)%24<<":"<<ptm->tm_min<<endl;  system("pause");  return 0;}

Method 4:

#include<iostream>#include<string>#include<vector>using namespace std;int main(){system("time");system("pause");return 0;}
