Question

Examine the following class diagram, additional information and answer the questions that follow: TV screenType: char screenSize: int resolution: string price: double standard: bool TV(char= 'L', int = 50, string ="HD", double = true) setOrder () :void display) :voicd getPrice() :double 600, bool etstandard() :bool; dditional Information: Method Remarks TV (char -L', int - 50, string -"HD", Constructor with default values. The double = 600, bool = true) positional arguments are screenType. screenSize, resolution, price and standard Set the data members accordingly. [Note- Screen type 'O' stands for OLED and 'L' stands for LCD. Screensize is can be "HD" and "UHD Assessor for data members, price and standard Prompt the user to enter the screenType, screenSize and resolution. The default price $600 is for standard size (50 inch). screen type (LCD) and resolution(HD). If there is any change to standard values, set standard to false. If the screenType is 'O' add $300. If the screenSize is greater than 50 inch, add $20 for LCD TVs and $40 for OLED TVs for each additional inch. If the resulution is UHD, add $200 for LCD TVs and $400 for OLED TVs. Update the price accordingl Uses cout to display the respective data members. If standard is true, displays "Standard TV". If standard is false. displays "Customised TV" getPrice ) :double getstandard ) :bool setorder ) :void display ) :voicd
