Literals are data used for representing fixed values. They can be used directly in the code. For example: 1, 2.5, ‘c’ etc.

Here, 1, 2.5 and ‘c’ are literals. Why? You cannot assign different values to these terms.

Here’s a list of different literals in C++ programming.

A variable name can only have alphabets, numbers, and the underscore _.A variable name cannot begin with a number.It is a preferred practice to begin variable names with a lowercase character. For example, name is preferable to Name.A variable name cannot be a keyword. For example, int is a keyword that is used to denote integers.A variable name c…[Read more]

Polymorphism is a concept in object-oriented programming that allows different objects to be treated as if they are of the same type. In Java, polymorphism can be achieved through two mechanisms: method overloading and method overriding.

In Java, encapsulation is a mechanism that allows you to restrict access to certain parts of an object’s state and behavior, and only expose a public interface for interacting with the object. Encapsulation helps to improve the maintainability, flexibility, and security of a program by preventing direct access to the internal workings of an object

In Java, the Singleton pattern is a design pattern that ensures that a class has only one instance, and provides a global point of access to that instance. The Singleton pattern is useful in situations where you need to restrict the number of instances of a class, such as when you need to control access to a shared resource or manage a system-wide…[Read more]

 Java, LinkedList is a class that implements the List interface and provides a way to store a collection of elements as a linked list. In this answer, I will explain how to use LinkedList in Java, as well as some of its commonly used methods.

Java, an OutputStream is an abstract class that represents an output stream of bytes. It is the superclass of all classes representing an output stream of bytes. The OutputStream class provides a standardized interface for writing data to different output destinations, such as files, network connections, and byte arrays. Here is an example of how…[Read more]

A function definition provides the actual body of the function. The C++ standard library provides numerous built-in functions that your program can call. For example, function strcat() to concatenate two strings, function memcpy() to copy one memory location to another location and many more functions.
