It is a new way of creating 1 and implementing a user-defined data type.
Object Oriented Programming With C++ – Balagurusamy – Google Books
Object-based programming languages, and 2. A function can also return a reference. In OOP, the concept of inheritance provides the idea of reusability. Remember, while applying inheritance we usually create objects using the derived clasB, Thus, it makes sense for the derived class to pass arguments to the base class constructor.
It is obvious that H irrespective of the place of definition, the function should perform the same- task. These functions are called member functions.
Operator overloading is discussed in detail oopz Chapter 7. The mechanism of deriving a new class from an old one is called inheritance for derivation.
Inheritance, when used to modify and extend the capabilities of the existing classes. It inserts or sends the contents of the variable on its right to the object on its left Fig.

As with long and short, if we use the const modifier alone, it defaults to int. An educational institution wishes to maintain a database of its employees. It may be either e member opos or a friend function. Il rsturiiH a complex type value. For instance, the reuse of a vy that has already been tested, debugged and used many times can save us the effort of developing and testing the same again. Test the function using a main program, 4. That ia, we can have more than one function with the siiniK name in out program.
FD3 – Fixed deposit p. It allows the data and functions to be hidden, if necessary, from external use.
The function does not have access to the actual variables in the calling program and can only work on the copies oosp values. O A derived class with onlv one base class is called single inheritance. A class can now use all the three visibility modes as illustrated below: The technique of hierarchical decomposition hag been used to specify the tasks to be completed for solving a problem. The variables declared, inside the dasfl are known as data members and the functions are known as member function.!

But it is also commonly u. This means, constructors of all the member objects should be called before its own constructor body is executed.
However, we may invoke the function defined in A by lifting the scope resolution operator to specify the class. Each object is associated bslaguruswamy the data of type class with which they are created- A class is thus ft collection of objects of similar type.
Thu constructor functions do not support this operation.
Preprocessor macros are popular in C. In ANSI C, we can also assign a void pointer to a non-void pointer without using a cast to non-void pointer type. Enter size of matrix: We con access m using the pointer ip as follows: POP has two major drawbacks, vie, 13 data move freely around the program and are therefore vulnerable to changes caused by any function in the program, jand 2 it does not model very wulL the rcal-wurld problems.
The client uhhh the server through the public interface of the dass- 1 2. This implies that the argument belongs to the source class and is passed to the destination class for conversion. We can perform any operations on it For instance, in the above class definition, the member function setvalO sets the values of elements of the array a[ 1, and display 1 function displays the values. C requires all the variables to be defined at the beginning of a scope.
This can be extended to cover other operators as well. O The derived class inherits some or all of the properties of the base class. DO may be invoked as follows: Similarly, when more than one constructor function is defined in a class, we say that the constructor is overloaded. The variable it is an alternative to the array element nllft]. They cannot be overridden. Here H p is an object of type person.
Similarly, I he AtnlCrticrlt x t putdata ; would display the values of data members Remember, a member function can be invoked only by iininy an ibjeci loflhH.
Their actual use appears elsewhere in the scope, sometimes faraway from the place of declaration. Remember, we have defined objects balaguruuswamy the earlier examples without using such a constructor. Communication with an object is feasible as long as it is alive.
