C++ Program to Calculate Area of Rectangle using Objects and Classes. Calculate Area of Rectangle: Area = Length x width - In C++, we are using Objects and Classes to calculate the area of the rectangle. The syntax of a class specification is given below: class classname { private: data_members; member_function; public: data_members; member_function; }; The syntax for creating objects of a class is: classname object1, object2, object3,…,; Video Explanation: How the Program is working.

MATLAB Simulator Q . Why we are using simulation software? A. Simulation Software helps us to predict the behavior of a system (i.e., Dynamic System ).  Q. How we can use simulation software? A. We  can use simulation software to evaluate a new design, diagnose problems with an existing design, and test a system under conditions that are hard to reproduce, such as a satellite in outer space.   Q.  Who using Engineers simulation software and why?  A.  Engineers and scientists use simulation software for a variety of reasons.  Creating and simulating models is less expensive, t o  t est different designs  before building one in hardware and  to test the integration of the full design.  Q.  What is  Simulink? A. A  simulation and model-based design environment for dynamic systems  integrated with MATLAB.  Simulink is developed by MathWorks. Q.  Why    Simulink is used? A.  Simulink is used for  modeling, simulating and analyzing multi-domain dynamic systems.  it is a 

Arguments Passing Techniques C++ is the mother of Object-Oriented Programming. Arguments Passing is a Process of transferring data between the calling function and the called function. In C++,  there are three ways by which arguments can be passed. Pass By Value Pass By Address or Pass By Pointer Pass By Reference Video Explanation:  C++ Program to swap two numbers with the third variable.     https://youtu.be/pq9VWQswqwo Video:  Call By Value Most of the programming languages like C use only the first two modules (i.e., Passing by Value and Address) whereas C++ supports all the three methods of passing arguments. Pass By Value: It is a default method for argument passing. When an argument is passed by value than a copy of the argument is made and passed to the newly created formal arguments in the called function. The formal arguments contain a copy of actual arguments which is stored in the separate memory location.   Program to Show How Pass By Value Work
