Reading txt file(different number in each line) and store in a vector

[EmanCS]

I have a text file that contains 40 lines
Each line contains different number of integers. For example:
17 18
20 33 41 44
50
55 60 66

Is is possible to read all these integers and store them in one vector?

Yes, it is possible to read every integer value from your file and store them in a vector.

Have you already written some code you could share with us, or are you waiting for us to do all the work?

Sure, but what do you plan to do with them when you've got them?

#include <iostream>
#include <fstream>
#include <vector>
using namespace std;

int main()
{
   vector<int> V;
   ifstream in( "data.txt" );
   for ( int x; in >> x; ) V.push_back( x );    // read all integers in file into V

   for ( int e : V ) cout << e << ' ';
}

17 18 20 33 41 44 50 55 60 66

if you did double vector you could keep the file structure, if you care about it?
