Difference Between Inheritance and Polymorphism

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. Content: Inheritance Vs Polymorphism Comparison Chart Definition Key Differences Conclusion Comparison … [Read more...]

Difference Between Abstraction and Encapsulation

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...]

Difference Between Structure and Union

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...]

Difference Between Structure and Class

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. The Structure and class, are almost similar in all respect except the significant one difference that, structure by default have all its member as “public”, and class by default have all its member “private”. Furthermore, polymorphism and inheritance are not supported by the structure, but classes support polymorphism … [Read more...]

Difference Between Array and Pointer

Array and pointer both are programming elements. An array is a data structure that holds variables of the same data type. On the other hand, the pointer is a kind of variable that holds the address of another variable which has the same data type as of pointer variable. We can even use a pointer to access the array elements. Accessing the whole array using pointer arithmetic, makes the accessing faster. While implementing an array a fixed memory size is allocated to array elements. … [Read more...]

Difference Between for and while loop

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 several 'for' loop variations in C++ are implied to increase its applicability, power and flexibility. For example, the for loop allows us to use more than one … [Read more...]

Difference Between while and do-while Loop

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. On the other hand, the do-while loop verifies the condition after the execution of the statements inside the … [Read more...]

Difference Between Virtual and Pure Virtual Function

The virtual function and pure virtual function both are the concepts of run time polymorphism. 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 definition in the base class, and all the inheriting derived classes has to redefine it. However, the virtual function is also called as dynamic dispatch and run-time dispatch, … [Read more...]

Difference Between Call By Value and Call by Reference

Call by value and call by reference are two different techniques to call a function or a method in a program. The call-by-value technique only passes the values of the variables. On the other hand, call by reference technique passes addresses of the variables. If you are passing arguments to a function using the 'call by value' technique, then changes to the variables inside the function won't affect the original values of those variables. If you pass arguments to a function using the … [Read more...]

Difference Between One-Dimensional (1D) and Two-Dimensional (2D) Array

An array is a collection of variables that are of similar data types and are alluded by a common name. 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 data type, whereas the two-Dimensional array is ‘array of arrays’ having similar data types. A specific element in an array is accessed by a particular index of that array. Arrays in Java work differently as compared to C++. C++ do not … [Read more...]
