Beginner having getline issues

I am working on a module program that has a function that opens a file
then the next file is to read the names from txt. file

Into an array guestlist there are 25 elements
I am getting a undeclared identifier error inFile but infile worked fine in my initial function.
Here is my code

Code:

---

#include <iostream>                // include standard I/O library
#include <fstream>                                                                      // opening and closing files

        PrintIntro();

 //open file that contains stars name
        OpenFile(inFile);

        ReadFile();

 
      return 0;

}

        cout << "********************************************************"
                  << endl;

                return;

}              // Print intro

        void OpenFile(ifstream& inFile)


 {
        inFile.open("partyGuests.txt");
       
        if (!inFile)
        {
       
                cout<< ("This file is unaccessable at this time!")<< endl;
                exit (1);

        {while(!inFile.eof())

        cout << guestlist << endl;

        //close file
        inFile.close();
       
        return
        }

error messages as follows (if I remove final function it compiles and debugs)

Code:

---

This is a prject and I have limited knowledge I would like to get over this hump
and have the array set so I can fill the parallel array
and do the comparisons.
This program is to have a user enter a name and test for present or absent
if absent change to present.

Hope this post is not to wordy thought it might help to know where it was heading.
Thanks for any help

You probably want to pass the inFile variable as a parameter to the ReadFile function (like you did with OpenFile).

It has nothing to do with getline and everything to do with that you do not understand scope.
Variables created inside one function is not visible outside it.

In general, in addition to the scoping problems as already noted:

Code:

---

void ReadFile ();

...

void ReadFile(string)
{
    while(!inFile.eof())
       
    Infile.getline(guestlist,NUM_GUESTS);
       
    cout << guestlist << endl;

    //close file
    inFile.close();
       
    return
}

#1 The prototype for the function and its actual definition do not match, one has nothing between the parenthesis and the other just has the keyword string which is incorrect.

#2 The language is case-sensitive. This means that Infile is not the same as inFile which I'm guessing you would rather use.

#3 You are using eof to control a loop which is bad. This will typically result in the last line being "processed" twice. A better method would be to place the getline call in place of the check against eof and test the return value.

#4 You're use of guestlist is wrong. It is an array of strings and as such you must use an index to access (either read into or write from) elements contained within it.

#5 There are two main variants of the getline function. You appear to be attempting to use the one for reading into character arrays but you want the one designed for use with string containers. They look a bit different.

#6 You need a semicolon after the return statement.

Also:

Code:

---

#include <cstdlib>
#include <string>                                                                      // set string class
#include <stdlib.h>  // Get rid of this

Thanks for the input. I am reading everything I can on scope and understand it. I had an idea it was wrong. embarrassed about the sloppy syntax. Is it possible to pass inFile to the next function? Thanks again I will stay up late working on this as it does not come naturally to me but I am tenacious.

>> Is it possible to pass inFile to the next function?

Yes, you already did it with OpenFile. Do the same thing with ReadFile.
