Dynamix array is also known as Vector, Dynamic array is an array that resizes itself up or down depending on the number of content. Linked lists have both advantages and disadvantages. The advantage of linked lists is that they can be expanded in constant time. While creating dynamic arrays, we must allocate memory for a certain number of… Read More »
Write a C++ program to check whether a given number is positive, negative or 0. Examples : Number = -44 Output: Negative Number = 0 Output: 0 Number = 50 Output: Positive C++ implementation : Output : Positive number Note that number 0 is neither negative nor positive. Please write comments if you find anything incorrect. A gentle… Read More »
Vector usually deals with primitive data types like int, string, double. However, there would be complexities and overhead arising when dealing with vector of class objects. For example, what will be output of below C++ program. How many constructors will be called here? How many constructors will be called? How many destructors will be called? The output of… Read More »

Almost each & every object oriented programming language is equipped with a special feature known as ‘static’ keyword. ‘static’ is such a keyword which can be used or written in front of any member variable or member function of a class. Now, what happens to that member variable or function if it is preceded by that ‘static’ keyword?… Read More »
OOP stands for Object-Oriented Programming. Procedural programming is about writing procedures or functions that perform operations on the data, while object-oriented programming is about creating objects that contain both data and functions. Object oriented programming languages are various but the most popular ones are class-based. Languages used in Procedural Programming: FORTRAN, ALGOL, COBOL, BASIC, Pascal and C.
