The System Console Explained

Generally, the system console represents a text terminal, which means that it accepts and visualizes just text without any graphical elements like buttons, menus, etc. It usually looks like a black colored window like this one:

In most operating systems, the console is available as a standalone application on which we write console commands. It is called a Command Prompt in Windows, and a Terminal in Linux and Mac. The console runs console applications. They read text from the command line and print text on the console. In this book we are going to learn programming mostly through creating console applications.

In the next examples we will read data (like integers, floating-point numbers and strings) from the console and will print data on the console (text and numbers).
