Having trouble opening a text file

[etothen]

Hello! Good morning!

I'm trying to do some math with a text file that looks like:

Mary Baggins 30000 20000 0.10
Tom Clark 20000 2000 0.08
Mark Twain 25000 10000 0.05
Rebecca Brown 10000 100 0.02

, where each column is clearly char, int, int and float.
I declared the above variables in class as public variables.
Using the while loop, I want to read the data correctly line by line and 'cout' the entire data.
Also, I want to use loop statement to perform operations with the int and float variables.

The following is my code:


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

class myclass{

public:

char A[20];
int B;
int C;
float D;

float Total;

float addition (int secondcolumn, int third, float fourth)
{ float sum = secondcolumn + third + fourth;
return sum; }

};

int main()

ifstream textfile;
textfile.open("textfile.txt", ios::in);

myclass data;

if(textfile.is_open())

{

while (textfile >> data.A >> data.B >> data.C >> data.D)
{
cout << data.A <<" " << data.B << " "<<data.C <<" " <<data.D << endl;
} // I thought this part would print the data out, but it didn't work..


textfile.close(); }

return 0; }




================


The code compiles, but shows nothing once I execute it.
In addition, I added an else statement to check if the file was open correctly.
The else statement does not appear, so my text file was read correctly.
I am expecting it to show the data I input.

Also, I would like to do some math with the numerical data line by line, but cannot find a way to write the code.

I appreciate your help in advance!

textfile >> data.A reads Mary. >> data.B tries to read Baggins into int but fails. So body of loop is not executed.

If you have two words, you need to read them both.
