Programming input and output with Visual Basic Script

CScript and WScript are two scripting engines used in the Windows operating system to run scripts written in VBScript and other scripting languages.

CScript is a command-line-based scripting engine that runs scripts in a command prompt window. It is primarily designed for running scripts that require no user interface or graphical output and is often used for system administration tasks. CScript is typically used for running scripts in batch files or scheduled tasks, as it provides more control over the execution of the script.

On the other hand, WScript is a GUI-based scripting engine that can display graphical output such as message boxes and dialog boxes. It is primarily designed for running scripts that require user interaction or display information to the user. WScript is typically used for running scripts from within a graphical environment, such as the Windows desktop or Windows Explorer.
