Step by step
Solved in 2 steps
- T/F: Instance variables are shared by all the instances of the class. T/F: The scope of instance and static variables is the entire class. They can be declared anywhere inside a class. T/F: To declare static variables, constants, and methods, use the static modifier.T/F A method defined in a class can access the class' instance data without needing to pass them as parameters or declare them as local variables.We use the _____ operator to create an instance of (object in) a particular class.
- Dynamic Games Instructions: Write a class called Game that contains a video game’s name, genre, and difficultyLevel. Include a default constructor and destructor for the class. The constructor should print out the following message: “Creating a new game”. The destructor should print out the following message: “In the Game destructor.” Include appropriate get/set functions for the class. In main(), prompt the user to enter the number of games he or she has played in the past year. Dynamically create a built-in array based on this number (not a vector or object of the array class) to hold pointers to Game objects. Construct a loop in main() that executes once for each of the number of games that the user indicated. Within this loop, ask the user to enter the name and genre of each game. Using a random number generator, generate a difficultyLevel between 1-10 (inclusive). Seed this random number generator with 100. Next, dynamically create a Game object (remember that this…Employee Class (Medium) Write a class named Employee that has the following member variables: name. A string that holds the employee’s name. idNumber. An int variable that holds the employee’s ID number. department. A string that holds the name of the department where the employee works. position. A string that holds the employee’s job title. The class should have the following constructors: A constructor that accepts the following values as arguments and assigns them to the appropriate member variables: employee’s name, employee’s ID number, department, and position. A constructor that accepts the following values as arguments and assigns them to the appropriate member variables: employee’s name and ID number. The department and position fields should be assigned an empty string (""). A default constructor that assigns empty strings ("") to the name, department, and position member variables, and 0 to the idNumber member variable. Write appropriate mutator functions that…Parent Class: Food Write a parent class called Food. A food is described by a name, the number of grams of sugar (as a whole number), and the number of grams of sodium (as a whole number). Core Class Components For the Food class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use validity checking on the parameters where appropriate a toString method that returns a text representation of a Food object that includes all three characteristics of the food Class-Specific Method Write a method that calculates what percent of the daily recommended amount of sugar is contained in a food. The daily recommended amount might change, so the method takes in the daily allowance and then calculates the percentage. For example, let's say a food had 6 grams of sugar. If the daily allowance was 24 grams, the percent would be 0.25. For that same food, if the daily allowance was 36 grams, the…
- In order to use the assignment operator on an instance of a class data type, it must be overloaded. Group of answer choices True FalseChild Class: Vegetable Write a child class called Vegetable. A vegetable is described by a name, the number of grams of sugar (as a whole number), the number of grams of sodium (as a whole number), and whether or not the vegetable is a starch. Core Class Components For the Vegetable class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use instance data variables where appropriate a toString method that returns a text representation of a Vegetable object that includes all four characteristics of the vegetableJavaC++ oop using classes only You are going to make an employee management system. In this lab, you have to create anEmployee class only. Employee class fields are: Employee Name, Employee ID, andEmployee Gender. The member functions include the getters and setters for all the membervariables and display () function to display the data. In the main function, first create twoEmployee objects and allow the user to enter data in these objects. Secondly, display thedata from these objects.
- True or False: 1. Data items in a class may be public. 2. Class members are public by default. 3. Friend functions have access only to public members of the class.Employee and ProductionWorker Classes Create an Employee class that has properties for the following data: Employee name Employee number Next, create a class named ProductionWorker that is derived from the Employee class. The ProductionWorker class should have properties to hold the following data: Shift number (an integer, such as 1, 2, or 3) Hourly pay rate The workday is divided into two shifts: day and night. The Shift property will hold an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Create an application that creates an object of the ProductionWorker class and lets the user enter data for each of the object’s properties. Retrieve the object’s properties and display their values.Animal Lab The objective of this assignment is to give you some practice using inheritance, virtual functions, and polymorphism. Instructions: Create a base class called Animal. All animals have a name (i.e. “Fido,” “Thumper,” “Princess,” “Nemo,” etc.) and an age. Provide a default constructor that initializes the age to zero and outputs the message “Invoking the default Animal constructor” and another constructor that allows the name and age to be set by the client. This other constructor should also output the message “Invoking the 2-argument Animal constructor.” Also construct a destructor for this class that outputs the message “Invoking the default Animal destructor.” Your Animal class should have a function called Move that cannot be implemented. That is, it should be declared as a purely virtual function. Your class should also have Get and Set methods to allow the name and age to be accessed. From the Animal class, derive Dog, Rabbit, Fish, and Snake classes. The derived…
