C++ - an introduction:

  C++ was developed by Bjarne Stroustrup. It is an object-oriented programming language. It is an extension of C.

Features:

• Cross-platform language: It can be executed in multiple platforms.
• High performance: code execution is efficient.
• Standard Template Library: it has a rich set of library functions.
• Compatibility: it is compatible in C.
• Extensibility: the user can create new data types which makes the language extensible.
• Exception handling: the exceptions are handled robustly.
• Memory management: it supports both static and dynamic memory allocation.
• Multi paradigm development:It supports procedural, object oriented and generic programming.

let us create a simple c++ program to display a message.

C++ program to display a message:

First, include a built -in header file

#include<iostream.h>

Next, include a namespace std. it includes the standard input and output functionalities.

Using namespace std;

Create a main() function with return type as int.

‘int main()’

{

}

Include the code between the { }

‘cout<<” Welcome to C++ world”;’

Finally, compile and run the program to get the output.

Here, is the program and output.

Program:

#include <iostream>

using namespace std;

int main() {

    cout<<" Hi, welcome to C++ world";

    return 0;

}

Output:

Hi, welcome to C++ world

Yes. The first c++ program to display a message is done.

Let us get the username and display a hi message to the user.

Try it in c++.

Steps:

• Use the above code and modify it as follows.
• Declare a string variable name.
• Create an output statement for getting the user’s name.
• Read the name from the user.
• Display the name with hi message.

Have you tried?????

Please check with the below program…

#include <iostream>

using namespace std;

int main()

{

  string name;

  cout << "Enter your name"<<endl;

  cin >> name;

  cout <<"Hi,"<< name <<",Have a nice day!";

  return 0;

 }

Output:

Enter your name

Rajeeva

Hi,Rajeeva,Have a nice day!

Hope, you understood the program flow. Keep coding!!!!!
