can someone help and teach me how to use this symbol \ and what is it for? I often see it in statements & have no idea :<

Answer 1

Add the statements here which you don't understand...

The symbol \ is used in eacape sequence. The \ symbol before sone characters makes it special purpose character..
\n => new character
\r => carriage return
\\ => include \ in string.
\b => back space character.
\" => add quote " In string.
May be some more...

Hope it helps...
