我想编写一个C ++代码来检查该人是否超过18岁，但不是通过询问年龄而是通过该人的DOB。有什么方法可以帮助我从系统获取当前日期？

最佳答案

#include <iostream>
#include <ctime>

void printTime() {
    time_t t = time(0);
    struct tm * timeStruct = localtime(&t);
    std::cout << (timeStruct->tm_year) << '-' << (timeStruct->tm_mon) << '-'<<  (timeStruct->tm_mday) << std::endl;
}
