is there a way to access a string like you access an char array? ex: char *name = "John Smith"; string name1 = "John Smith"; letter = name[3]; //letter would equal 'n'; // how would you do this for string name? edit: string name is changed to string name1 for clarity.

I would do it like this:

std::string name = "John Smith";

char letter = name[3]; //letter would equal 'n';

I believe that the [] operator is overloaded so that you can access your string as name1[index]. There''s also name1.at(index1). And if you''re really desperate, you can get a c-style string from name1.cstr().

Read more carefully. Hanz altered your original post to change name to std::string, indicating that operator[] was already overloaded for it to behave just like it would with a null-terminated char array.
