Using a file, structures, passing parameters

[LightningOdin44]

I am supposed to use functions outside of main to load a structure of speakers with information from the user, and then access each piece of information from a file. I know there are errors when I try to use pass by reference and when I am trying to use a file. Every line makes sense to me, but I know there are issues and I'm looking for someone to help point me in the direction of my errors so that I may fix them. Yes, some parts are unfinished and I am working on them.

  #include <iostream>
#include <fstream>
#include <string>
using namespace std;

/*
Project Name: SpeakersBureau
File Name: SpeakersBureau
		Status: 
Start Date: 09/19/2019
End Date:   09/
		The program is designed to store to, read from, and write to a file with basic information 
		from ten different speakers in a Speaker's Bureau. It has a menu that allows the user to destroy 
		and enter data, edit his or her data, print his or her data, or exit the program. The program 
		makes sure all data is entered else it prints an error message. Functions are delegated by main.

		This program was done entirely by me and no part of this program was plagiarized,
		intentionally or unintentionally, from anybody. I would be held accountable and 
		penalized if any part of this program was plagiarized.

Would you mind telling us what parts you think have errors and what parts you are just working on?

Using code tags is helpful, thank you.

I know there are errors when I try to use pass by reference and when I am trying to use a file.

We don't know what the errors are, the crystal ball is fogged over.

Tell us what the errors are the compiler spits out. The full errors, not a condensed version please.

Since you are reading data from a file we also need an example of the data the file contains.

In manageData you call enterData(), editData() and printData() functions before you define them, without doing a forward declaration.

Even when you get that fixed each function uses parameters you pass to the functions, yet you call the functions without passing anything.

Your formatting is a mess, making it harder to notice potential problems.

WAY to many errors. Your bool function "openInFile" doesn't end - you're missing a bracket. string "input.txt" is not a valid argument for a function. You can instead say "string name = "input.txt"", but there's no point since you type it out in the function anyway.
