Step by Step solution about How to resolve the algorithm Keyboard input/Obtain a Y or N response step by step in the Mathematica/Wolfram Language programming language

This Wolfram language code creates a dialog box that prompts the user with the question "Yes or no? [Y/N]". The user can respond by typing the letter "Y" for yes or "N" for no.

Depending on the user's response, the code prints either "You said yes" or "You said no" and then closes the dialog box.

Here's a detailed breakdown of the code:

CreateDialog[TextCell["Yes or no?[Y/N]"]]: This line creates a dialog box with the specified text "Yes or no? [Y/N]".

NotebookEventActions -> {

• ** "KeyDown" :>**: This specifies that the code should respond to the "KeyDown" event, which occurs when a key is pressed on the keyboard.

• Switch[ToUpperCase@CurrentValue["EventKey"],: This line uses the "Switch" function to determine the action to take based on the key that was pressed.

• "Y", Print["You said yes"]; DialogReturn[]: If the user presses the "Y" key, the code prints "You said yes" and then closes the dialog box using "DialogReturn[]".

• "N", Print["You said no"]; DialogReturn[]: If the user presses the "N" key, the code prints "You said no" and then closes the dialog box using "DialogReturn[]".

]: This closes the "NotebookEventActions" specification.

Overall, this code provides a simple way to create a dialog box in Wolfram language and handle user input based on specific key presses.

CreateDialog[TextCell["Yes or no?[Y/N]"],
  NotebookEventActions -> {
    "KeyDown" :> Switch[ToUpperCase@CurrentValue["EventKey"],
      "Y", Print["You said yes"]; DialogReturn[],
      "N", Print["You said no"]; DialogReturn[]
      ]}];
