wxString str = "Hello, world!"; int len = str.length(); wxPrintf("The length of the string is %d", len);
wxString str2; str2.Printf("This string has %d characters.", str.length()); // str2 now contains "This string has 13 characters."This example demonstrates how the length method can be used in conjunction with the Printf method to create a new string. Here, a new wxString object "str2" is created and initialized using the Printf method. The argument passed to the Printf method is the result of calling the length method on the "str" object, which is then used to fill in the %d placeholder in the format string. The resulting string is then stored in "str2". The package library associated with wxString and wxPrintf functions is wxWidgets.
