Answer 1

It's uses differs according to your language .
Generally it is used to print special character like(',",%,/,& etc) cause when you use these character in print function
It has other meaning
Like if you want to print( "hello world") with colon

You will face problems

Ex if your syntax ish

Printf(""hello world"");

It will result error

So the syntax will be

Printf("\" hello world \" ")

Thats why it is used

Answer 2

Smart Niraj Singh ,hi
I think you talk about the escape character, you could do a search on it.
It is used to specify in a string not to interpret the caracter just after, for example \n will induce a line break and there are some others rules or examples why to use it before a particular caracter.
But it is called "escape caracter" if you look for more complete explanation.
