In C, the '\n' character is a special type of character called a control character, these are characters that do something other then just display themselves, here is all the ones that I know:
\n = newline
\t = tab
\a = This one rocks, it makes the computer make a beeping sound
The difference between those follows:
Say you called the first one, then the user entered 'hello', j would now be 'hello', if you called the second one, j would be 'hello\n' and whenever you printed out j after the second one, it would print out hello followed by a newline
\n = newline
\t = tab
\a = This one rocks, it makes the computer make a beeping sound

It discards unwanted white space.
A white-space character in the control string causes scanf() to skip over one or more leading white-space characters in the input stream.
