There isn't a realloc() or a redim() in C++. You have to declare a new char[20]. Copy the old one to the new one. And finally, delete the old one.
Reply:with built-in functionality you can't...you want to use one of the common libraries such as cstring which can do resizing etc.
Reply:In C++ you can use STL's as these inbuilt data structures does a lot of work with minimal code.
