Reading/writing .txt files into an array

Dec 2nd, 2007

I am writing a program and I have a .txt file that has a some information about people. I would like to write that information into an array and then display that information about the person.

The problem is that I don't know how many names will be in the .txt file, or how to write that information to the file.

Here is what I have so far.

using namespace std;

	infile.open ("hourly.txt");
	while (!infile.eof())

int main()
{
	const int size = 20;
	HourlyEmployee a[size];
	HourlyEmployee fellow;
	HourlyEmployee person(10, 55, "Electronics", "Alan", "Good", "E1234") ;
 
	fellow.display();
	person.display();
 
 
 
 
	return 0;

	infile.open ("hourly.txt");
	while (!infile.eof())
	{

	}

}

int main()
{
	const int size = 20;
	HourlyEmployee a[size];
	HourlyEmployee fellow;
	HourlyEmployee person(10, 55, "Electronics", "Alan", "Good", "E1234") ;

	fellow.display();
	person.display();


	
		
	return 0;
}

and here is my hourlyEmployee class.

I don't really know how to put the .txt information into the array so if anyone could give me some idea's or any help at all that would be great.

Thanks
