Hello, and welcome to the wonderful world of C++ programming! Today, we will introduce you to the basics of C++, navigate the CodeSignal IDE that comes pre-packed with C++, and acquaint you with the concept of code comments. Ready? Let's dive right in!

C++, a high-speed and powerful programming language, has been in use for decades and still ranks as a top language. From video games and robotics to operating systems and web servers, C++ serves as a versatile tool. However, as the saying goes, with great power comes great complexity. Once you adapt to C++, you can overcome efficiency and flexibility barriers!

As we solve problems, you'd need an ideal tool to write and run your programs. That's where CodeSignal's IDE comes into play! It comes pre-equipped with the necessary libraries to run C++, saving you from the hassle of installations.

A C++ program comprises one or more function definitions. The program's operation commences from the main function.

Here's the basic structure of a program:

The first line includes the iostream library, which equips the program for input and output operations.

Don’t worry about understanding every line of the code just yet. It will be covered in more detail in the following lessons. For now, you need to know that when a C++ file is run, the function runs, and that prints “Hello, C++!” to the console.
