Inheritance allows, code reusability and the polymorphism is, the occurrence of one function with different form. The basic difference between inheritance and polymorphism is that inheritance allows the already existing code to be reused again in a program, and polymorphism provides a mechanism to dynamically decide what form of a function to be invoked.

Abstraction is a process of collecting important information which will create a base for building up a complex system. Encapsulation is a process of making a complex system easier to handle for an end user, without worrying about its internal complexities. The basic difference between "abstraction" and "encapsulation" is that abstraction focuses on "identifying the necessary components for building a system" whereas, encapsulation focuses on "hiding the internal complexities of a … [Read more...]

C++ allows all the five ways that the C language provided to create a custom data. Those five ways are 'structure', 'bit-field', 'union', 'enumeration', 'typedef'. In the article below we are going to study the difference between structure and union. The structure and union both are the container data types that can hold data of any "type". The one major difference that distinguishes structure and union is that the structure has a separate memory location for each of its members whereas, the … [Read more...]

Both a structure and a class provides a way to create a customized data type which can be used further to create instances. C++ expands the role of structure to create a class. Both structure and class, are similar in all respect except one difference that, structure by default have all its member as "public", and class by default have all its member "private". Let's study the difference between structure and class by using comparison chart. Content: Structure Vs Class Comparison Chart … [Read more...]

There is a close relationship between array and pointer. The pointer can be used to access the array elements, accessing the whole array using pointer arithmetic, makes the accessing faster. There is a basic difference between a pointer and an array that is, an array is a collection of variables of similar data type whereas the pointer is a variable that stores the address of another variable. There are some other differences between an array and a pointer which are discussed below in the … [Read more...]

In C++ and Java, the iteration statements, for loop, while loop and do-while loop, allow the set of instructions to be repeatedly executed, till the condition is true and terminates as soon as the condition becomes false. Conditions in iteration statements may be predefined as in for loop or open-ended as in while loop. There are some major differences between for and while loops, which are explained further with the help of comparison chart. Content: for Vs while Comparison Chart … [Read more...]

Iteration statements allow the set of instructions to execute repeatedly till the condition doesn't turn out false. The Iteration statements in C++ and Java are, for loop, while loop and do while loop. These statements are commonly called loops. Here, the main difference between a while loop and do while loop is that while loop check condition before iteration of the loop, whereas do-while loop, checks the condition after the execution of the statements inside the loop. In this article, we … [Read more...]

The virtual function and pure virtual function both are the concepts of run time polymorphism. Polymorphism is supported by both the languages C++ and Java. In Java, the term "overriding" is used instead of 'virtual function', as the virtual function is the term of C++. The main difference between 'virtual function' and 'pure virtual function' is that 'virtual function' has its definition in the base class and also the inheriting derived classes redefine it. The pure virtual function has no … [Read more...]

In C++ and Java, there are two ways to call a function or a method. The first is "call by value" and the second is "call by reference". Call by value method passes only the value of a variable to the function code, and if there is any change in the value of a variable inside that function it does not affect the original value of that variable. In call by reference method, we pass the variable itself in an argument, and the change in the value of a variable also affects the original value of that … [Read more...]

An array is a collection of variables that are of similar data types and are referred by a common name. A specific element in an array is accessed by a particular index of that array. Arrays in Java work differently as compared to C++. The main topic of our discussion is the difference between One-dimension and Two-Dimension array. A one-dimensional array is a list of variables with the same datatype, whereas the two-Dimensional array is 'array of arrays' having similar data types. C++ do not … [Read more...]
