/* This program will compute the temperature of a gas using the gas law.*/

#include<iostream>
#include<fstream>
#include<iomanip>
#include<cmath>

using namespace std;

int main()
{

    double velocity, time, distance, counter = 1, a;
    
    
    ifstream infile ("R:distanceIn.txt");
    ofstream outfile ("C:distanceOut.txt");
    

    if (infile.fail())
    {
                      cout << "Error. Unable to read file" << endl;
                      return 0;
    }
    
    else
    {    
    
    outfile << "       Car under constant acceleration" << endl;
    outfile << "\n" << setw(8) << "Initial Velocity  " << "Time  " << "Acceleration  " << "Distance " << endl;

    
    while (counter < 3 && !infile.eof())
    {
    infile >> velocity >> time;
    
    while ( counter < 6 && !infile.eof())
    {
          infile >> a;
          
          distance = velocity + 0.5 * (a*(pow(time,2)));
          outfile << setw(7) << velocity << setw(16) << time <<setw(13)<< a<<setw(18)<< distance;
          outfile << endl;
          counter++;
          }
    counter++;         
          
    }
    infile.close();
    }
    
    return 0;

}



Trying to do a while loop within another while loop. The one within works, but the main while loop goes through only once.


Here are the data from my input and output files:

     10               5            5              72.5
     10               5            6                85

The inner loop exits when "counter" is greater then or equal to 6. By the time the outer loop evaluates "counter" again it has to be greater then 3.

I got it. I ended up using a for loop then a nested for loop, and it worked. Thanks.
