There was no compile time error. However, the outputs produced were not the correct one.

i have added the following modificaiton to the code:

A change in getData() to check for end of file
A change in main() to make the program enter into the while. It was returning from before entering the loop
Statements to update information about players.

modified program:

Modification made are given in bold letters. It is for the reader's reference. It is better option to copy adn paste this in your editor.
