reading into Struct from file

[bcianfrocca]

I need to open a file that looks something like this:

45, Owen, Terrance, Tight End, Green Bay Packers
35, Green, Josh, Quarterback, New England Patriots

and so on...

i need to read this information into a structure i guess, along the lines of:

struct newInfo
{

     int number;
     char lastName [];
     char firstName [];
     char position [];
     char team [];
}

how would this be done??

What have you done so far?

Please post some code and we'll help!

here's all i have so far... as soon as i get the info into the struct properly, i'll be well on my way to doing what i need with the information... here's the code...

#include <iostream>
#include <stdlib.h>
#include <math.h>
#include <fstream.h>
#include <string>



struct initInfo
{
	int number;
	char lastName [20];
	char firstName [20];
	char position [5];
	char college [20];
	char nflTeam [30];

};


int main()
{



	ifstream playersFile;
	initInfo info;
	char c;

	playersFile.open ("players.txt");

	if (playersFile.fail())
	{
		cout<<"An error occured while trying to open the file."<<endl;
		system ("PAUSE");
		exit (1);
	}

	cout<<"File opened"<<endl;
	
	
	

	while (!playersFile.eof())
	{
		cin.getline(info.number, ',');
		cin.getline(info.lastName, ',');
	}

	
	playersFile.close();

	cout<<"number is: "<<info.number<<endl;
	cout<<"last name is: "<<info.lastName<<endl;



return 0;

}

Overload the stream extraction operator (>>) for the struct:

struct initInfo
{
    int number;
    char lastName [20];
    char firstName [20];
    char position [5];
    char college [20];
    char nflTeam [30];
};

istream& operator>>(istream& is,initInfo& rhs)
{
    // Your code here... maybe use "getline" as a start
    // followed by some further processing
}

int main()
{
    initInfo info;
    ifstream playersFile;

    ...

    while ( playersFile >> info )
    {
        cout<<"number is: "<<info.number<<endl;
        cout<<"last name is: "<<info.lastName<<endl;
        ...
    }

    ...

}

Maybe overload the stream insertion operator (<<) as well...?

#include <iostream>
#include <stdlib.h>
#include <math.h>
#include <fstream.h>
#include <string>

I'd suggest replacing those with these:

#include <iostream>
#include <cstdlib>
#include <cmath>
#include <fstream>
#include <string>

What?? I don't understand what you mean by overloading the operator?? and what is

istream& operator>>(istream& is,initInfo& rhs)

What is rhs? Can you explain what this line does?

istream& operator>>(istream& is,initInfo& rhs)

That is overloading the operator. It's basically a function prototype. The name of the function is operator>>, which tells the compiler that you're overloading the operator, ">>". When you overload an operator you define behavior for it so you can use it with your own data types. Inside the parentheses are obviously the parameters - which will be the operands used in the statement with your operator.
