in need of help

[drdodirty2002]

hi all I need advice here I'm having a bit of a dilemma with this algorithm. We just started reading info from a text file check it out.

#include < iostream.h >
#include < fstream.h >

struct person
{
	 int id;
  float gpa;
  char name[19];
};

class myclass
{
private:fstream f;
		person p;
		
public: void display1( )
		{
			char line[80]; fstream f;
			f.open("data.txt" , ios::in);
			while( true )
			{
			
				f.getline(line, 19, '\n');
				
				f>>p.id>>p.gpa;
				if(!f.fail())
					break;
			}
			f.close();
		}

		void display2( )
		{
			f.open("data.txt", ios::in);

			f>>p.id>>p.gpa;
		
		while(!f.eof())
			{
				 cout<<p.id<<"\t"<<p.gpa<<endl;
				 f>>p.id>>p.gpa;
			}
		f.close();
		}

void display(char *fname)
	{
		f.open(fname, ios::in);
		while(true)
		{
			f>>p.id>>p.gpa;
			if(f.fail()) break;
			cout<<p.id<<"\t"<<p.gpa<<endl;
		}
		f.close();
		}
};

void main()
{
	myclass cs131;
	cout<<"This is the content of the file\n";
	cs131.display1();

	cout<<"This is the content of the file\n";
	cs131.display2();

	cout<<"This is the content of the file\n";
	cs131.display("data.txt");
}

Anyways I can't seem to get the name to print out no matter what I do anyone have any ideas

I see:

f>>p.id>>p.gpa;

but I don't see where you read anything into p.name in display(), display1(), or display(2). In display1() you do read something into a local char array calle line:

f.getline(line, 19, '\n');

but then you do nothing with line once you have read something into line.
