i have doubt in VARIABLE NAME in C language????

[soni.pankajkumar]

doubt in c language

in 'C' language we consider '_' as a Character,so can we have '_' as a first letter of any variable name,if please give me the reason???[/b]

Yes, an identifier can start with '_'.
Does the question arise because you found that a character '_' was appended at the beginning of a variable name by the compiler?

Hi,
Yes, we can have "_" as a first character for a variable name, but usually it is advised not to do so because all the system variables have their names begining with "_" as the first character.

is not a problem to use it .but once they are exported to assemble modules you will end uop with variables names with two underscores !

Can you >>> Yes you can,
Reason >>> you can guess it if you opened any header file or library file in a text document where you will find too many identifiers starts with the same char '_'
I hope that helped

Ahmad,
