Introduction to C++

Welcome to the world of C++! C++ is a powerful programming language that is widely used in various domains, including networking and engineering, especially in the field of finance.

If you have an entry-level understanding of C++ and have watched YouTube videos and online classes for about a year, you're in the right place to deepen your knowledge and practice various C++ concepts.

C++ provides a rich set of features and libraries that allow for efficient and high-performance coding. In this lesson, we will provide you with an overview of the C++ programming language and its features.

Let's start with a simple C++ program that prints 'Welcome to C++!' to the console:

1#include <iostream>
2using namespace std;
3
4int main() {
5  cout << "Welcome to C++!" << endl;
6  return 0;
7}

This program uses the iostream library and the cout object to output the message 'Welcome to C++!' to the console. The endl is used to insert a newline character and flush the output stream.

Feel free to modify the code and experiment with different outputs. Running C++ programs will help deepen your understanding of the language and its syntax.
