How to read TSV (tab-separated values) in C++

This post is also available in: deDeutsch (German)

This minimal example show your how to read & parse a tab-separated values (TSV) file in C++. We use boost::algorithm::split to split each line into its tab-separated components.

#include <fstream>
#include <iostream>
#include <string>
#include <vector>
#include <boost/algorithm/string.hpp>

using namespace std;
using namespace boost::algorithm;

int main(int argc, char** argv) {
    ifstream fin("test.tsv");
    string line;
    while (getline(fin, line)) {
        // Split line into tab-separated parts
        vector<string> parts;
        split(parts, line, boost::is_any_of("\t"));
        // TODO Your code goes here!
        cout << "First of " << parts.size() << " elements: " << parts[0] << endl;
    }
    fin.close();
}
