haha kya baat hai plz reply don't spoil ur time and knowledge

what you mean imprince?

[KHUBBU]

Its Simple, its used instead of "space" like "Room_No" will look more appropriate and can be easily understood that its the room number, if we take "Roomno" it wud not be that much clear. and lastly we cannot give space between a variable name coz then it will be taken as different words like " Room No".

I hope this clears ur confusion. if u have other alternative u can use it of course.

There is a reason for that. a space is taken as a blank characer and the variable name's can't have blank space b/wn them so to make it look seperate we use the underscoe' _ " since it is valid. and spaces are not allowed on the internet too.... so we all use "_"

Think cooljeba and the other guys are right..space is not accpeted in a variable name hence we use the "_" instead.
"_" has significance in C language as system variables(of the compiler generally) start with "_"
^if thts not true..pls tell me..coz my Comp sirs sometimes wrong!

There could be another reason

Since "_" is very small and it's position is very low...

People can read text with "_" as easily as they can do it with " "

People_can_read_text_with "_" as_easily_as_they_can_do_it_with " "

It*wouldn't*work*with*any*other*character*SEE!!!

i also think so . its more readable then others ..
