Getting date and time from a .txt

本文关键字：时间 取日期 获取 txt      更新时间：2023-10-16

我正在尝试从我拥有的文件中获取日期和时间，该文件如下所示

"Run01"
"‹L˜^’·","ŽžŠÔŽ²","Äضޓú•t","Äضގž"
"70000 DIV","100ms (1ms/S)","17-03-25","06:16:15.49"
"Á¬ÈÙ","±ÝÌß","“dˆ³Ž²","ºÒÝÄ","½¹°ØݸÞ","•ÏŠ·”ä","µÌ¾¯Ä","̨ÙÀ"
"CH1-1","8956 H-SPEED","200mV","Detector11","OFF","-","-","OFF"
"CH1-2","8956 H-SPEED","200mV","Detector12","OFF","-","-","OFF"
"CH2-1","8956 H-SPEED","200mV","Detector21","OFF","-","-","OFF"
"CH2-2","8956 H-SPEED","200mV","Detector22","OFF","-","-","OFF"

其中日期和时间位于第 3 行 2 逗号(，(之后

我对谷歌上的例子有点困惑。有人知道我该怎么做吗？

编辑*我添加了一些我到目前为止所做的工作， 

#include <iostream>
#include <fstream>
#include <string>
const int LINE = 4;
int draft(){
    std::ifstream fdate("DataFile0001/DataFile_B0001_info.txt");
    std::string s;
    for (int i = 1; i<= LINE; i++)
        std::getline(f,s);
    std::cout << s;
    return 0;
}

老实说，我不想编译和运行它，而只是root draft.cc因为我将使用它来处理我拥有的根文件。但这更像是一个 c++ 问题，而不是根源问题。在这里问我觉得更合适

for (int i = 1; i<= LINE; i++)
{
    std::getline(f,s);
    if(i == 3)
    {
        size_t pos = s.find_first_of(",");
        pos = s.find_first_of("," , pos+1);
        std::string date = s.substr(pos+2 , s.find_first_of("," , pos+1)-pos-3);
        pos = s.find_first_of("," , pos+1);
        std::string time = s.substr(pos+2 , s.length()-pos-3);
        std::cout << date << std::endl;
        std::cout << time << std::endl;
        break;
    }
}
