Instructions

Objective

Write a program that will implement file and string parsing in C language.

Requirements and Specifications

Assignment Overview

OVERVIEW

Write a C assignment program to generate sport team win-loss records from game results in files.

NOTE: This is a harder assignment than the previous major assignments.

OBJECTIVES

• Use file I/O (text mode).
• Use C-style strings and string functions.
• Use best practices for magic numbers.
• Design computer programs for modularity and maintainability.
• Demonstrate the development cycle for C programs.
• Follow stated requirements.
