使用C ++中的向量在新行上显示文本文件中的列

Question

I've been trying to display 2 rows with 6 columns, on different rows. I've tried different methods, none of which seems to be working. This is what I have for now:

void Travel::LoadDest()
{

    ifstream file("worlddeals.txt");
    vector<vector<string>>data;

    if (file) {
        string line;
        while (getline(file, line)) {
            data.push_back(vector<string>());

            stringstream split(line);
            string value;

            while (split >> value)
                data.back().push_back(value);
        }
    }
    for (int i = 0; i < data.size(); i++) {
        for (int j = 0; j < data[i].size(); j++)
            cout << data[i][j] << endl;

        cout << '\n';
    }
}

In my .txt I have:

Corfu [Tab] 5* Gelina Village Waterpark [Tab] 21 May 2017 [Tab] Luton [Tab] 10 nights [Tab] All Inclusive

Holguin [Tab] 5* Paradisus Rio De Oro [Tab] 22 May 2017 [Tab] Manchester [Tab] 10 nights [Tab] All Inclusive

What I want the output to be is:

Corfu

Accommodation: 5* Gelina Village Waterpark

Departure Date: 21 May 2017

Departure Airport: Luton

Duration: 10 nights

Board Basis: All Inclusive

---

Holguin

Accommodation: 5* Paradisus Rio De OroStar

Departure Date: 22 May 2017

Departure Airport: Manchester

Duration: 10 nights

Board Basis: All Inclusive

Answer 1

You said it's not working out for you, but I just tried that code I linked using your input data, and it printed out pretty much what you want. I didn't print the field names, but here is the line parsed according to your specifications:

#include <iostream>
#include <sstream>

void print_tab_delimited_fields(const std::string &input)
{
    std::istringstream ss(input);
    std::string token;
    while (std::getline(ss, token, '\t')) {
        std::cout << token << '\n';
    }
}

int main()
{
    std::string line1 = "Corfu\t5 * Gelina Village Waterpark\t21 May 2017\tLuton\t10 nights\tAll Inclusive";
    print_tab_delimited_fields(line1);

    std::string line2 = "Holguin\t5 * Paradisus Rio De Oro\t22 May 2017\tManchester\t10 nights\tAll Inclusive";
    print_tab_delimited_fields(line2);
}

output

Corfu
5 * Gelina Village Waterpark
21 May 2017
Luton
10 nights
All Inclusive
Holguin
5 * Paradisus Rio De Oro
22 May 2017
Manchester
10 nights
All Inclusive

It would be a trivial change to push the results to a vector, or just print them along with the field labels, since the data file is already assumed to have those exact fields in that exact order.
