Transcription: Once a class has been defined in C++, objects of that class can be manipulated in much the same way as objects of built-in types. Therefore, you can work with objects in your application using the same C++ code you might use for built-in types. For example, in the Shed Building program, you can add, subtract, multiply and divide fractions using the same operators that add, subtract, multiply and divide integers and floating point numbers.
