C++中获取当前时间并格式化输出

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

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

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

     return ;
 }

输出结果为：
