Hello, I have a question about the char **argv array in then main function of a any C/C++ program.

I know that char* is a pointer to a string, but how does ** make it an array?

Could this syntax be used for other array types like "int *my_array" or is specific to char?



Also if I have a const vector<int>, do I need a special iterator like

const_vector<int>::iterator

or can I use a normal vector<int>::iterator ?



thanks.

A char * is a pointer to an array of chars.
A char ** is a pointer to an array of pointers to arrays of chars.

Yes, the syntax can be used for anything else.

For the second question, you need to use a const_iterator.

So, vector<int>::const_iterator
