Question
Write a program countfile.c that calculates and prints on screen the number of bytes or number of lines in a file.
To print the number of lines in the file myfile.txt, the program is run from the command line with two arguments as follows
 
countfile.exe -l myfile.txt
 
or, to print the number of bytes in the file myfile.txt, it would be run as
 
countfile.exe -b myfile.txt
 
EXAMPLE:
Suppose the file myfile.txt contains the following
 
samantha
jacob
58
91
 
Then running 
countfile.exe -l myfile.txt
would print 4 on the screen.
 
And running 
countfile.exe -b myfile.txt
would print 15 on the screen.
 
If as a switch anything other than -l or -b is used, the program should give an error message and exit with code 1.
If the file is not found, then it should give a message saying no such file exists, and exit with code 2.
If everything runs correctly the program should return 0.
