reading from a file and classes

well im stuck again and its because of classes again. i have the follwing program that works fine but i need to make a class and use the code as a function of that class

Code:

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

display a file on the screen
int	main(void)
{
	const int	FileNameLen = 30;	// Constant int
	ifstream	infile;			// file object
	char		filename[FileNameLen];	// Store the filename
						// as a character string
	char		inchar;		//Read a character at a time


	// Get the file name
	cout << "Enter file name ->" << '\t' ;
	cin >> filename;
	// Open the file
	infile.open(filename);
	
	if (!infile)	{
		cerr << "Cannot open " << filename << endl;
		exit(1);
	}

        // Read the file
	while (!infile.eof())	{
		inchar = infile.get();
                cout << inchar;	//display it on screen
	}
	infile.close();	//Close the file	
	return(0);
}

this is what i have so far but it gives me a few errors, and im totally lost, someone help me out?

Code:

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


const int	FileNameLen = 30, ArrayLen =4;	// Constant integer

class array
{
public:
		int readarray();
		array();
private:
	
		ifstream	infile;			// file object
		char		filename[FileNameLen];	
						
		char		inchar;		//Read a character at a time
};
array::array()
{

}
// display the file 
int	readarray()
{
	
	// Get the file name
	cout << "Enter file name ->" << '\t' ;
	cin >> filename;
	// Open the file
	infile.open(filename);
	// If you can't open the file, print error message
	if (!infile)	{
		cerr << "Cannot open " << filename << endl;
		exit(1);
	}

        // Read the file
	while (!infile.eof())	{
		inchar = infile.get();//This reads in
					
                cout << inchar;//Display it on screen
	}
	infile.close();	//Close the file	
	return(0);
}
int main()
{
		array Numbers;

		int nums = Numbers.readarray();
		cout <<"The numbers in the array "<< nums << endl;

	return 0;
}

i have narrowed it down a bit more, any suggestions pelease, this is what i got so far

Code:

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

const int    FILENAMELEN = 30, ArrayLen = 4;

// The class array
class    array    {
public: // These functions are avaiable for use outside the class 
    inline int    getsize()    {return(size);}
    void        readarray(void);
    array();

private:
    //Private - available only to member functions
    int    x[ArrayLen];
    int    size;
};

//initialization constructor 
array::array(void)
{
    size = 0;
}

void array::readarray(void)
{ 
    ifstream infile;
    char filename[FILENAMELEN];
    char inchar;

    cout<<"Enter filename->" <<'\t';
    cin>> filename;
    //openfile
    infile.openfile(filename);
    //if you cant open the file, print error message
    if (!infile)
    {
        cerr<< "Cannot open " <<filename << endl;
        exit(1);
    }

    //Read the file character
    while (!infile.eof())
    {
        inchar = infile.get(); //this reads in even whitespaces
        cout << inchar; //display it on screen
    }
    infile.close();
    return(0);
}

int    main()
{
    array    myarray;


    myarray.readarray();
    return(0);
}

but im getting 1 error where i have commented

Code:

void array::readarray(void);
{

See it?

If i remove the semicolon i get 5 errors instead of 1 that i was getting before. This is really getting on my nerves, im stuck on this the whole day. I cant even think anymore. Jesus help me lol

edit: since you know more than i do i took your advice and removed the semicolon, i got 5 errors instead of 1 so i tryed to figure them out. Turns out i have typed FILENAMELEN using camel notation on the declaration and captial letters when i was using it. yet i still get 1 error

Code:

openfile' : is not a member of 'ifstream'
        c:\program files\microsoft visual studio\vc98\include\fstream.h(98) : see declaration of 'ifstream'

edit: i have corrected the code, and im still getting the above error

1. your headers should look like:

Code:

#include    <iostream>
#include    <fstream>
#include    <cstdlib>

you were using the old headers (with .h) hence the deprecated comment.

2. ifstream doesn't have member openfile - it is simply called open.

thats correct . i clicked the line under the error and i read it, then i clicked List members and looked all the memebers and only "open" was a valid assumption so i used it and it worked.

Thanks a lot Andy, now i can work on the rest of this prog. rejoice!!
