Question

Use MATLAB

Write a Brownie class

It should have two properties: an integer, "yield" which is how many brownies a batch produces, and a logical "chocchips", which true if the recipe uses chocolate chips and false if not.

Both properties should be given default values

Write two methods: a constructor function which uses the values passed to it (if any) or the default values if not; also overload the disp function so that the output is as shown in the following example:

>>mochab = Brownies(16,true)

mochab =

This recipe yields 16 brownies and has chocolate chips

>>bettyc = Brownies(20,false)

bettyc =

This recipe yields 20 brownies and does not have chocolate chips

>>disp(bettyc)

This recipe yields 20 brownies and does not have chocolate chips

Answer 1

%   MATLAB Program for brownies

classdef Brownies
    properties
        yield
        chocchips
    end
    methods
        function obj = Brownies(y,c)
            if nargin == 0
                obj.yield = 10;
                obj.chocchips = false;
            else
                obj.yield = y;
                obj.chocchips = c;
            end
        end
        function disp(obj)
            if obj.chocchips == true
                disp(['This recipe yields ' num2str(obj.yield) ' brownies and has chocolate chips']);
            else
                disp(['This recipe yields ' num2str(obj.yield) ' brownies and does not have chocolate chips']);
            end
        end
    end
