You cannot use a menu. Your program must read the user's choice directly into the card suit variable (of an enum type). (Note: You cannot overload operators for built-in types, but enumerations are, technically, user-defined types. Therefore you can overload input/output operators for them.) This proof of conceptapplication will help show your programming team that the bridge game you are designing can accept bids directly from the player without having to rely on a clumsy menu interface.

Base is nonzero positive integer while exponent is positive integer. Call this power method within function button_click of windows form class that reads integer values for base and exponent from user and performs the calculation written in the power method of Exponents class. If returned value is even it should display on label otherwise display it on textbox. Built-in functions are not allowed to use.(Assume label name lblDisplay and textbox name txtDisplay)This is in c++ The base class Pet has private data members petName, and petAge. The derived class Dog extends the Pet class and includes a private data member for dogBreed.

The first class is the class Shape. The Shape class has two float type properties: center_x and center_y. The Shape class also has the following methods: a constructor Shape(), that will set center_x and center_y to zero. set/get functions for the two attributes 1) You need to implement two additional functions for Shape: setCenter(float x, float y), that will set the new center and print: Figure moved to [<center_x>, <center_y>] draw(), that will print: Drawing Figure at [<center_x>, <center_y>] 2) You will have to implement another class, called Triangle, which inherits from the Shape class. The Triangle class has one int attribute: side. The Triangle class has the following methods: a constructor that will receive one int parameters (side) set/get for its attribute setCenter(float x, float y), that will set the new center and…
