fgets()
The fgets function reads up to the num-1 characters from stream and stores then in character array pointer to by str.
Character are read until either a newline or an EOF is received or until the specified limit is reached. After the characters have been read,
a null is stored in the array immediately after the last character read. A newline character will be retained and will be the part of array pointed to by str.
