3. Print the first 5 lines of a file (lastnameHEAD.c):
Write a C program that takes a file as an argument and prints its first 5 lines (equivalent to using
head -n 5). If this program does not receive the correct number of arguments, or if it fails to
open the given file, it should return errors.
Hint: Write a function readLine() that reads characters until it hits a newline character -- run
this function in a loop to get and print 5 lines. Assume that the file has at least 5 lines.
