Description
Learning Goals
==============
This assignment asks you to write a program that reads lines from a file,
counts how many times a word occurs, and report the result.
You will learn to
* Read lines and store as strings
* Detect whether one string is inside another string
Read Line from File and Count Words
===================================
This assignment uses `fgets` to read strings from a file, uses
`strstr` to find whehther a word is inside the string from the file.
This assignment is a simplified version of the `grep` command in
Linux.
What To Do
==========
You need to write a function called `countWord(char * filename, char * word, char * line, int size)`
that opens a file named `filename`, counts the number of occurences of given word in the file,
and returns it. If `fopen()` fails, return -1, and **DO NOT** fclose.
Further instructions are in the comments in the function in file `filestr.c`.
WHAT TO SUBMIT
==============
You **must** follow the instructions precisely. Failing to follow
these instructions will likely make you receive zero in this
assignment. Your score **is determined by your submission**, nothing
else. The teaching staff is strictly prohibited seeing anything on
your computer for grading.
