transfering inputFile to vector c++

[sesslit805]

We're supposed to Write a program that reads an unknown number of integers from a data file called “data.txt” into a vector of integers named V. V is initially empty and grows as the user reads data from file.

Once done copying data into vector V, you need to print the contents of V (write a function print that prints the contents of a vector of any size) and perform some other tasks on the vector as described below.

This is the data file: 5 6 12 87 100 28 35 66 77 29
EVERY TIME I RUN THIS CODE IT OUTPUTS: 5 12 100 35 77

#include <iostream>
#include <vector>
#include <fstream>

using namespace std;

int main()
{
  vector <int> v;
  int count;
  int tmp;

    ifstream inputFile;
    inputFile.open("data3.txt");

    if(!inputFile)
      {

        cout << "File does not exist";
      }

    else
      {
        while (inputFile >> count)

          {
            cout << count <<" ";
            v.push_back(count) ;
            inputFile >> count;
          }
        inputFile.close();

      }


    return 0;
}

        while (inputFile >> count)

          {
            cout << count <<" ";
            v.push_back(count) ;
            inputFile >> count;
          }

You're reading twice but outputting once, which explains why the output skips every other number. Simply remove the line in question and it will work as expected.
