C/C++ 获取当前时间并格式显示

#include <string>
#include <time.h>
using namespace std;

string getTime()
{
    time_t timep;
    time (&timep);
    char tmp[64];
    strftime(tmp, sizeof(tmp), "%Y-%m-%d %H:%M:%S",localtime(&timep) );
    return tmp;
}

int main(){
    string   time = getTime();
    cout << time << endl;

    return 0;
}
