All of the following are true about a class EXCEPT: Oa function associated with a class is referred to as a subroutine. Oa class created in one source code file can be used in another source code file. Oa class is a blueprint for creating objects. Oa class can contains data, and methods to manipulate the data.
Which statement of the following is the most appropriate? Group of answer choices When you design a class, always make an explicit statement of the rules that dictate how the member variables are used. These rules are called the invariant of the class, and should be written at the botttom of the implementation file for easy reference.

Using C# language: Programming PLO-2 Measured: Design, implement, and evaluate computer solutions utilizing structured and object-oriented programming methodologies. Design a class named Contractor. The class should keep the following information: Contractor name Contractor number Contractor start date Write one or more constructors and the appropriate accessor and mutator functions for the class.
Indicate whether the statement is true or false. 13. The non-static methods of a class are called instance method. 14. A constructor has no type and is therefore a void method. 15. A class can have only two constructors. 16. In shallow copying, each reference variable refers to its own object. 21. The method finalize automatically executes when the class objects goes out of scope. 22. A mutator method of a class changes the values of data members of the class. 23. In java, the reference this is used to refer to only the methods, not the instance variables of a class. 24. Classes that are defined within other classes are called inside classes. 25. Modifiers are used to alter the behavior of the class 26. A constructor has the same name as the class. 27. Constructors are called like any other method. 28. You can perform some arithmetic operations on class objects.

The operator that is required to access members of classes and structs is called: a. Colon operator b. Scope resolution operator c. Operator overloading d. Member access operator e. None of the answers Answer: What is the name of the program that uses and interacts with the class? Answer: By assuming that all libraries are included, replace MYFUNCTION with the proper function name to make the code correct: 001010 111101101 01010101111110 1010101010101 111010101010 0101100 vector> MyVector; int rows= 10, cols = 4; MyVector.MYFUNCTION(rows, vector(cols, 100)); cout << MyVector [0] [1] << endl; for (int i } = 0; i < MyVector.size(); i++) { for (int j 0; j < MyVector[i].size(); j++) cout << MyVector[i][j] << " "; cout << endl;
Task-1: Both computer and software engineering programs blend the broad engineering discipline courses with the computer science specific courses. Hence, it is a good idea to represent the "course" as an object before attempting to write a program to help students get register to the courses. The programmer can think of the abstraction of a course object as the representation of title, code, and credit values only. Write a class declaration for the course object that includes a constructor, a set and a get member function for each data member, and a member function that returns the course information upon request. For instance, for this course it should prepare a string like “COMP218 - Object-Oriented Programming". a) Use C++-strings for the representation of string of characters. b) Use C-strings for the representation of string of characters.
1. A method stub is a) a short method b)a method with an abrupt end c)a method whose header has not yet been written d) a method whose statements have not yet been written 2 An abstract class can always be instantiated as an object can sometimes be instantiated as an object can often be instantiated as an object can never be instantiated as an object 3)When a derived class defines a member method that has the same name, parameters, and return type as a base class's method, the member method is said to overload the base class's method overreach the base class's method override the base class's method overshadow the base class's method 4. What would be the best code to print out all the elements of an array for (int i = 0 ; i <= arry.length ; i++ ) System.out.println(arry[i]); for (int i = 0 ; i < arry.length ; i++ ) System.out.println(arry[i]); for (int i…
1. Why should the attributes of a class be private? 2. Can a Time class definition that includes both of the following constructors: Time( int h = 0, int m = 0, int s = 0 ); Time(): be used to default construct a time Time object? if not, explain why. 3. Write a statement that creates a pointer to a Circle object and instantiates the Circle object being pointed to. Use dynamic memory and initialize the object to the value 5.
