as soon as you encounter a # its a comment till a new line is found.. thats it.
from new line again start the process.

Now consider what you can do with that tool. The example doesn't show all of the possibilities. You could use the # as your delimiter character which is the 3rd param of the function. If you are reading a config file you could loop and call getline for every line in the file using # as the delimiter. Comment lines won't even be read into the file. The lines that have comments at the end will only be read into the program up until the # character is reached. That could be useful so that you don't have to read unnecessary information into the program.
