const char* str = "hello"; wxString wxstr(str, wxConvUTF8);
wxString str1 = "hello"; wxString str2 = "world"; wxString result = str1 + " " + str2;
wxString wxstr = "hello"; const char* str = wxstr.mb_str();
wxString wxstr = "hello"; size_t len = wxstr.length();In summary, the wxString library in C++ provides an easier way to handle strings in your code. It is part of the wxWidgets package library that can be used for building GUI applications that can run on multiple platforms like Windows, macOS, and Linux.
