Association in UML can be represented by:
Suppose that the Test class does not have an overloaded assignment operator. What happens when an assignment a=b; is given for two Test objects a and b?
Peer-to-peer relationship is a type of _________.
Which of the following are good reasons to use an object oriented language.
To answer this question, we need to understand the benefits of using an object-oriented language. Let's go through each option to determine which ones are good reasons to use an object-oriented language:
Option A) You can define your own data types - This option is a good reason to use an object-oriented language. Object-oriented languages allow you to create and define your own data types, which can help you model real-world entities or abstract concepts more effectively.
Option B) An object-oriented program can be taught to correct its own errors - This option is not a good reason to use an object-oriented language. The ability to correct errors in a program depends on the specific development practices and tools being used, rather than on the choice of programming paradigm (such as object-oriented).
Option C) It is easier to conceptualize an object-oriented program - This option is a good reason to use an object-oriented language. Object-oriented programming provides a natural way to organize and structure code by modeling the problem domain as a collection of interacting objects. This can make it easier for programmers to understand and conceptualize the program.
Option D) You can define your own data types and It is easier to conceptualize an object-oriented program - This option is a good reason to use an object-oriented language. As explained above, both of these reasons (defining your own data types and easier conceptualization) are advantages of using object-oriented languages.
Based on the analysis above, the correct answer is D.
What is wrong with the following code? int * x = (int *) malloc(100 * sizeof(int)); x = realloc(x, sizeof(int) * 200);
An application uses encapsulation to achieve ________
To answer this question, you need to understand the concept of encapsulation. Encapsulation is one of the four fundamental principles of object-oriented programming (OOP), which aims to bundle data and methods within a single unit called a class.
Let's go through each option to understand why it is correct or incorrect:
Option A) Information hiding - This option is correct because encapsulation allows the hiding of the internal implementation details of a class. By encapsulating data and methods within a class, the internal workings are hidden from other classes or modules, promoting better security and maintainability.
Option B) Minimizing interdependencies among modules - This option is not directly related to encapsulation. While encapsulation can help to minimize interdependencies by providing a clear interface to interact with a class, it is not the primary purpose of encapsulation.
Option C) Make implementation independent - This option is not directly related to encapsulation. Encapsulation focuses on bundling data and methods together within a class, but it does not ensure implementation independence. Implementation independence can be achieved through other principles, such as abstraction and polymorphism.
Option D) All of these options - This option is incorrect because option B and option C are not directly related to encapsulation. Therefore, not all of the options are achieved through encapsulation.
The correct answer is option A) Information hiding. This option is correct because encapsulation allows the hiding of the internal implementation details of a class, promoting better security and maintainability.
