Passing argv

[vckngs7]

I am having difficulty passing argv using a custom class and then using the .size() function on it.

I am declaring the relevant function as follows within the class header file.

class.h

void useArgv(char**);

and then I am using as follows.

class.cpp

void customClass::useArgv(char* argv[]){
    cout << argv.size() << endl;
}

and in main . . .

main.cpp

int main(int argc, char *argv[]){
    . . .
    customclass.useArgv(argv);
    exit(0);
}

I get an error as follows.

class.cpp:4: error: request for member ‘size’ in ‘argv’, which is of non-class type ‘char**’

I do not understand why I am able to pass argv in this way but not use the .size() function on it.

You can't call size() on a pointer. argc contains the number of arguments so pass that to the function to use instead.

Yes, I figured that out RIGHT after I posted this. I left the post in case someone else had overlooked the same thing. Thanks.
