  Functions in C++ Hello! Everyone in the previous blog we have discussed about classes and object in c++ and how to create and how to access these classes and its member function. But in this tutorial we will discuss about function and its overloading in c++ What is function? As you listened word function and overloading of function first question that will come to your mind that what is this function and why we are studying This. So i am giving few points about function, so that you can get some idea about function: 1.function is a Self contained block of statements that performs that performs a coherent task of some kind. 2.Every C++ program can be thought of the collection of functions. 3.main() is also a function. Type of functions There are mainly two type of functions in c++. 1.Library function 2.user defined functions: that means programmer can create their own function to perform a specific task. Uses of functions 1.Writting functions avoids rewri...

  Classes and object in c++ Hello! Everyone in the previous tutorial we have learned about object orientation of c++, in this tutorial we will learn about classes in c++ and how to create class and how we deal with it. SMART ENGINEERS What Is class? A class is a user define data type which holds both data and function. The data included in the class i.e the internal data is called data member and the functions included is called the member function. these member function can manipulate the internal data of the class. A class definition starts with the keyword class followed by the class name; and the class body, enclosed by a pair of curly braces. A class definition must be followed either by a semicolon or a list of declarations. For example, we defined the Box data type using the keyword class as follows:- class Box {    public:       double length;       // Length of a box       dou...

C++ OOPs concept Hello! In the previous blog we learned some basic terminology of C++, but in this blog we are going to learn the object orientation concept of C++ for which this language is famous.so let’s get started. The major purpose of C++ programming is to introduce the concept of object orientation to the C programming language. OOPs is a paradigm that provides us many concepts such as inheritance, data binding, polymorphism etc. SMART ENGINEERS Object -orientation Object orientation is basically a thinking methodology which describe following points. 1 .Everything is an object. 2 .Any system is composed of object (a system is also an object). 3 .The evolution and development of a system is caused by the interactions of the objects inside/outside a system. Everything is an object Any entity that has state and behaviour is known as object.    1 .A student, a professor    2 .A desk, a chair, a classroom, a building    3 .A univers...

   Introduction to c++ Hello! everyone I hope you all are doing great in this period. In the previous tutorials we have learned about c language, and we covered all important topics related to c language. Now we will learn c++ language and important topics related to c++. SMART ENGINEERS What is c++ ? C++ is a general-purpose programming language that was developed as an enhancement of the C language to include object-oriented paradigm.it is an imperative and a compiled language. Some of the features & key-points to note about the programming language are as follows: Simple:- It is a simple language in the sense that programs can be broken down into logical units and parts, has a rich library support and a variety of data-types. Machine Independent:- A C++ executable is not platform-independent (compiled programs on Linux won’t run on Windows), however they are machine independent. Mid-level language:- It is a mid-level language as we can do both systems-p...

  Array Hello! Hope you all are doing great, in the previous blog we had learned many topic related to C, for example variable, operator, loops. In today’s blog we will start a new topic, we will learn to work with arrays. you will learn to declare, initialize and access elements of an array with help of simple example. What is array? As you listen word array what comes in your mind? That what is this array and why we are studying this. An array is a variable that can store multiple value but of same data type. For example, if you want to store 50 Integer, you can create an array for it. An array is a fixed sized sequenced collection of elements of same data type.it is simply a group of like type data.in its simplest form, an array can be used to represent a list of a number, or a list of names. Some example where the concept of an array can be used. 1.list of employees in an organization. 2.test scores of a class of students. 3.list of customers and their telepho...
