Hi karana,
Like this:

int main(int argc,char** argv){
    if(argc!=2){
        [error... not exactly one argument]
    }

    mkdir(argv[0]);
}

Cheers,
Stefan

> mkdir(argv[0]);
...should read
mkdir(argv[1]);

argv[0] is the program name itself, not the first argument.

If you intension is just creation of the directory 'xxx', add this line to the body of your main( ):

mkdir(argv[1]);

--supply the directory name as the first argument in the command line following the program name, while running the program.

karana,
> popen()
popen is very similar to system, it also has a full shell:

FILE* f=popen("mkdir your_dir","r");
/* Now you can parse mkdir's stdout via freads from f. But as mkdir is mute, not much use here */
pclose(f);

You could parse mkdirs stderr by redirecting it:
FILE* f=popen("mkdir your_dir 2>&1","r");

Then you can catch errors.
