// Creating a wxString wxString str = "Hello, world!"; // String concatenation str += " How are you?"; wxString name = "Alice"; str += wxString::Format(" My name is %s.", name); // Converting to a C string const char* cstr = str.ToStdString().c_str(); // Getting length and substring int len = str.Length(); wxString sub = str.SubString(7, 11);In these examples, we are using wxString to create and manipulate Unicode strings. We are creating a string, concatenating it with other strings and variables, converting it to a C string, and getting its length and substring. These operations demonstrate the basic features of wxString and its usefulness for working with strings in C++. wxString is part of the wxWidgets library, which is a cross-platform GUI toolkit for C++. It provides a wide range of tools and functionality for developing desktop and mobile applications, including support for multiple platforms, native widgets, and a rich set of controls and widgets.
