c++获取当前时间

#define _CRT_SECURE_NO_WARNINGS
#include <iostream>
#include <ctime>
#include <string>
using namespace std;


std::string getCurrentTime() {
   
	time_t now = time(0);
	tm *local = localtime(&now);
	char buf[80];
	strftime(buf, sizeof(buf), "%Y-%m-%d %H:%M:%S", local);
	return std::string(buf);
}

int main() {
   
	std::string current_time = getCurrentTime();
	std::cout << "当前时间: " << current_time.c_str() << std::endl;
	system("pause");
	return 0;
}

结果：
