Const keyword define constant values that cannot change while the program is running. A const variable must be assigned a value when it is declared. If we try to change its value after it has been initialized, we will get a compilation error. Use of const keyword with different parameters: Variables Pointers Function arguments and […]

When the static keyword is used, variable or data members or functions can no longer be changed. It is allocated for the lifetime of the program. The static keyword can be used with: Static Variables: Variables in a function, Variables in a class Static Members of Class: Class objects and Functions in a class Static Variables in […]

Constructor: A constructor is a special member function of a class and shares the same name as of class, which means the constructor and class have the same name. The compiler calls the constructor whenever a class object is created; it allocates memory to the object and initializes class data members with default values or […]

What is Function Overloading & why is it used? Function overloading is an object-oriented programming feature in which two or more functions have the same name but different parameters.The function overloading feature in C++ is used to improve code readability. It is used to save the programmer from having to remember multiple function names. Function […]

What is the Inline function & why is it used? When the program executes the function call instruction, the CPU saves the memory address of the instruction that follows the function call, copies the function’s arguments to the stack, and transfers control to the specified function. This process can occasionally result in overhead in function […]

Now, let’s look at some of the special member functions that can be defined in C++ classes. The following are the various types of Member functions: Simple functions Static functions Const functions Inline functions Friend functions Simple Member functions: These are the basic member function, which doesn’t have any special keyword like static etc. as […]

A member function is a function that is declared as a class member. It is declared within the class in any of the visibility modes, i.e. public, private, or protected, and it has access to all the class’s data members. If the member function is defined within the class definition, it can be defined directly […]

Members of a class can be accessed directly within the class by using their names. Accessing a member outside the class, on the other hand, is determined by its access specifier. The access specifier not only determines where the member is accessible in the program but also how it is accessible in the program. Note: […]

Access modifiers, also known as Access specifiers, are used to implement Data Hiding, an essential aspect of Object-Oriented Programming. Data hiding is an important feature of Object-Oriented Programming that allows program functions to avoid directly accessing the internal representation of a class type. The labeled public, private, and protected sections within the class body specify […]

The fundamental idea that the object-oriented approach revolves around in C++ is the concept of classes and objects. It increases the efficiency of the program by reducing code redundancy and debugging time. Classes: A class is the building block in C++ that leads to Object-Oriented programming. It is a user-defined data type with its own […]
