CString str = "Hello, world!"; const char* myString = str.GetString(); cout << "String Contents: " << myString << endl;
CString str = "The quick brown fox jumps over the lazy dog."; const char* substring = str.Mid(4, 5).GetString(); cout << "Substring: " << substring << endl;In this example, a CString object is created with the value "The quick brown fox jumps over the lazy dog.". The Mid method is then called on this object with the parameters 4 (the starting position) and 5 (the length of the substring to be extracted). The GetString method is then called on the result of the Mid method, and the returned pointer is stored in a const char* variable. Finally, the extracted substring is printed to the console. The CString class is part of the MFC (Microsoft Foundation Class) library.
