How to fix Error that leads to program Crash - c++

Question

For some reason or another I cannot figure out why the data when opened does not get put into arrays and the program crashes. I have searched around for a answer to no avail. I get the feeling I will be posting a here a few more times before I finish this program!
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
string bookTitle [14];
string bookAuthor [14];
int loadData (string pathname);
void showall (int counter);
int main ()
{
int counter;
string pathname;
cout<<"Input the name of the file to be accessed: ";
cin>>pathname;
loadData (pathname);
showall (counter);
cout<<"Press <Enter> to Exit";
cin.ignore();
cin.get();
return 0;
}
int loadData (string pathname) // Loads data from infile into arrays
{
fstream infile;
int counter = 0;
infile.open(pathname.c_str()); //Opens file from user input in main
if( infile.fail() )
{
cout << "File failed to open";
return 0;
}
while (!infile.eof())
{
cout<<"File Opened"; // I get the "File Opened" text and then a crash
infile >> bookTitle [14] ; //takes input and puts into parallel arrays
infile >> bookAuthor [14];
cout<<"Data Put in Arrays";
counter++;
}
infile.close();
}
void showall (int counter) // shows input in title(author) format
{
cout<<bookTitle<<"("<<bookAuthor<<")";
}
Edit: The assignment is to take a file with names in a format such as title
author
title
author
Then it must output the arrays to screen in a title(author) format.
After this I must make it a looping program so a search can be chosen of one of the arrays and returns the entry in a title(author) format.
Here is how the code stands now;
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
string bookTitle [50];
string bookAuthor [50];
int loadData (string pathname);
int showall (int counter);
int main ()
{
string pathname;
int counter=0;
cout<<"Input the name of the file to be accessed: ";
cin>>pathname;
loadData (pathname);
showall (counter);
cout<<"Press <Enter> to Exit";
cin.ignore();
cin.get();
return 0;
}
int loadData (string pathname) // Loads data from infile into arrays
{
fstream infile;
int counter = 0;
infile.open(pathname.c_str()); //Opens file from user input in main
if( infile.fail() )
{
cout << "File failed to open";
return 0;
}
while (!infile.eof())
{
infile >> bookTitle [counter] ; //takes input and puts into parallel arrays
infile >> bookAuthor [counter];
counter++;
}
infile.close();
}
int showall (int counter) // shows input in title(author) format
{
cout<<bookTitle<<"("<<bookAuthor<<")";
return 0;
}

Answer 1

A Quick problem I see is:
infile >> bookTitle [14] ;
infile >> bookAuthor [14];
Is incorrect, What you need is:
infile >> bookTitle[counter];
infile >> bookAuthor [counter];
Also,
The counter variable declared in main() and in loadData() are two different variables. The one declared in main()is never iniitalized at all.

Answer 2

There are many problems with this code.
Main problem
These lines write only into 14th elements of the arrays
infile >> bookTitle [14] ; //takes input and puts into parallel arrays
infile >> bookAuthor [14];
In order to fill the entire array you need to use the counter variable for index:
infile >> bookTitle [counter] ; //takes input and puts into parallel arrays
infile >> bookAuthor [counter];
BTW: if array's size is 14 then the maximum index is 13. So you can't access an element with index 14. And that's probably causes the crash.
Other problems I noticed
counter in main() is not initialized
showall() function takes an argument but does not use it, which is probably the index.
showall() call in main() probably needs to be in a loop, to show all elements.
