Consider the RationalNumber class declaration below. You need to write four functions: - A stand alone friend function that overloads the << operator and prints a rational number in the form numerator/denominator. - A member function that overloads the subtraction operator (-) for the RationalNumber class. The member function subtracts two RationalNumber objects r1 and r2 and assigns the result to object r3. - A standalone friend function that overloads the postfix increment operator ( ) for the RationalNumber class. The friend function adds one to a RationalNumber object and allows cascaded function calls. - A stand alone friend function that overloads the >> stream extraction operator and prompts the user for rational number (numerator and denominator)

Ap practice - performance task response the ap create performance task asks you to write about an abstraction that you developed and wrote into your code. most of the time that means identifying a function or procedure you wrote to "manage complexity" in your program. here is the actual prompt from the create performance task: 2d. capture and paste a program code segment that contains an abstraction you developed individually on your own (marked with a rectangle). this abstraction must integrate mathematical and logical concepts. explain how your abstraction manage the complexity of your program. (must not exceed 200 words) below is a segment of code from an "under the sea" program with a rectangle drawn around a portion of the code identifying an abstraction. imagine that you wrote this and are composing an ap response about how this abstraction manages complexity. (note: ignore the requirement that the abstraction integrate "mathematical and logical concepts" for this practice response. just write about managing complexity). explain how the abstraction marked with the rectangle in the code above manage complexity of this program. write your response here submit
