Thread: Not able to read data from text file and convert it to integer

Thanks all! it was really helpful. I am a noob.

@laserlight : I have changed my code as follows, but i don't know how do this -->

Then, use the return value of getline, not good(), to control the inner loop.

can you explain me in more details.

New code:

Code:

// reading a text file
#include <iostream>
#include <fstream>
#include <string>

using namespace std;

int main () {

 string line;
 int i,j,c;
 int Ncoil, Ntank;
 int **Tmin, **Tmax;
 
 char str[256];

 cout << "Number of coils to be cleaned: ";
 cin >> Ncoil;

 cout << "Number of tanks: ";
 cin >> Ntank;

Tmin = new int *[Ncoil];
ifstream myfile ("Tmin.txt");
if (myfile.is_open())
    {
        
            for (int i = 0; i <= Ncoil; ++i)
              {
                 Tmin[i] = new int[Ntank];
                 for(int j = 0; j <= Ntank; ++j)
                    {
                             getline(myfile, line, ' ');
                            while (???????)
                            {
                            c = atoi(line.c_str());
                            Tmin[i][j] = c;
                            cout<< Tmin[i][j]<<endl;
                            }
                    }
                    
             }
            myfile.close();
    }

else cout << "Unable to open Tmin file";
    
      
  
  return 0;
}
