Netspeak is not permitted here. You know how to spell 'you'.

Do you need this information inside the C program, or not?

Yes Sir may be a file program which could take a C program and in output give me the variables been declared..

Your reply contradicts itself, but whatever.

You will have to scrape the program source code for variable definitions. I'm trying to find if I had a program to do this before, but I know it won't be easy. Something that understands C well enough to tell between a function definition and a variable definition is halfway there to a proper C parser.

Symbol table doesn't help, since local variables don't appear in the symbol table.

What have you tried?

gdb cannot do that, it can only list global variables and currently instantiated variables.

What precisely is this for? The doxygen application can extract information on variables if you wish. It can do a lot more than that as well.

So Sir other way would be search for word like int, float etc and store the words after int,float till I get a semicolon.

Sir I am working with naming convention in c.. where in a user writes his/her program and i want to check if conventions are followed or not.. like if program is to find sum of two numbers so variables declared be atleast num1, num2 like that rather then a,b..
