To read from file and store data in map c++

I am trying to read file contents and store it in map data structure, where I am trying to skip comment section not be included in my map. I am unable to keep my map as expected, I am kind off clueless how to go ahead. I have mentioned how my map should look like. Please suggest me what changes I have to add in my code. Thanks in Advnc 🙂

Input file:

# Filename: MyFile
# Revision: 107

Items              Types       count     price
snacks             junkfood
Mango              fruit        5         50
strawbery          fruit        10        50
carrot             veggie
burger             junkfood
beetroot           veggie       4         20
cinnamon           masala

Expected output file:
Stored in map<string, string>
[key] [value]

Items      ->        Types       count     price
snacks     ->        junkfood
Mango      ->        fruit        5         50
strawbery  ->        fruit        10        50
carrot     ->        veggie
burger     ->        junkfood
beetroot   ->        veggie       4         20
cinnamon   ->        masala

CPP file:

#include <map>
#include <string>
#include <fstream>
#include <sstream>
#include <iostream>
#include <algorithm>
#include <iterator>

using namespace std;

typedef std::pair<std::string, std::string> attribute_pair;

void check(ifstream &inputFile, map<string, string> &diffm)
{
    diffm.clear();
    std::string line;
    while (getline(inputFile, line))
    {
       std::stringstream ss(line);
       attribute_pair attribute;

       while (ss >> attribute.first >> attribute.second)
       {
          if (attribute.first != "#")
               diffm[attribute.first] = attribute.second;
       }
    }
}

int main(int argc, char const *argv[])
{
    map<string, string> list1;
     
    if (argc >= 2)
    {
        std::ifstream inputFile(argv[1]);
        check(inputFile, list1);

        map<string, string>::iterator itr;
        for (itr = list1.begin(); itr != list1.end(); itr++)
        {
           cout << itr->first << "     " << itr->second << "\n";
        }
    }
    else
    {
        std::cerr << "Usage <prog name here> <filename1 here> <filename2 here>\n";
        return -2;
    }
}

>Solution :

I’m feeling generous, I am guessing somewhat at your requirements (particularly how the value part of the map is meant to be). I have not tested this code.

void check(ifstream &inputFile, map<string, string> &diffm)
{
    diffm.clear();
    std::string line;
    while (getline(inputFile, line))
    {
       if (line.empty() || line[0] == '#')
       {
           // skip blank or comment lines
       }
       else
       {
           std::stringstream ss(line);
           std::string key, value;
           // read first string (key)
           ss >> key;
           // read rest of line (value)
           getline(ss, value);
           diffm[key] = value;
       }
    }
}
