The document is a C++ program that implements a menu-driven calculator demonstrating various operators including arithmetic, increment/decrement, relational, logical, and bitwise operators. The user is presented with options to perform different operations using different data types, and the output displays results based on user inputs. The program continues to prompt the user until they choose to exit.
