Thread: command line args

Hi,

every where I see

Code:

int main(int argc, char *argv[])

if i write

Code:

int main(int a, char **b)

is this OK to write like this..
or any problem is there... Please explain.

thanx

Both are correct

The function called at program startup is named main. The implementation declares no
prototype for this function. It shall be defined with a return type of int and with no
parameters:
int main(void) { /* ... */ }
or with two parameters (referred to here as argc and argv, though any names may be
used, as they are local to the function in which they are declared):
int main(int argc, char *argv[]) { /* ... */ }
or equivalent;**) or in some other implementation-defined manner.

**Thus, int can be replaced by a typedef name defined as int, or the type of argv can be written as
char ** argv, and so on.

thanks for ur reply...

here what i want to know is

whether "argc" and "argv" are keywords...or I can use any names....
I got this doubt just now and I dont have C compiler to test it.

thanx
