- PLZ help with the following: After working with DIR command and its switches, you realize that you always use /O and /P. Windows stores important settings in an area of memory called the Windows environment. The settings in the Windows environment are assigned to environment variables. An environment variable is a symbolic name associated with a specific setting. To assign a setting to an environment variable, use the SET command. Its syntax is SET variable = string , where variable is the name of the environment variable, and string is the setting you want to assign to the variable. SET DIRCMD=/P / O Note that it’s not a space between DIRCMD and the equal sign. You may see the contents of Windows environment, type SET and then press Enter. To remove the DIRCMD variable and its settings from the environment, type SET DIRCMD= and then press Enter. 1.What is the setting of your PATH environment variable ? 2.What is the meaning of this sequence of directories ?1.

The nodes arranged in a layout container are a combination of controls and possibly other layout containers. All of the above statements are true. When the user interacts with a control, it generates an event. Programs can use event handling to specify what should happen when each user interaction occurs. An event handler is a method that responds to a user interaction. An FXML GUI's event handlers are defined in a controller class.

- NumericAnalyzer will accept a list of 1 or more numbers as command line arguments. NOTE: Don’t prompt the user for input – this is an exercise passing values to your program via the command line! We’re forcing the user to “push” data values to the application rather than “pull” it from the user! Error checking: if the user fails to pass in parameters, the program will display an error message (of your choice) and exit early. EXTRA CREDIT (+5) Data Validation – flag non-numeric parameters as “invalid data” and exit early. The main() method’s String [] args argument values must be converted and assigned to a numeric/integer array and passed to an instance of NumericAnalyzer. (SEE EXAMPLE main() IMPLEMENTATION BELOW). main() should also be responsible for error checking logic. Your program will display the following information about the numbers provided by the user: The set of numbers provided by the user sorted ascendingly. NOTE: DO NOT implement your own sort algorithm! Part…This type of parameters allows us to omit including the parameter name and simply provide the value and it would work just fine. One example is the -Name parameter in the Get-Command This is why the Get-Command Get-Help cmdlet works the same as the Get-Command -Name Get-Help cmdlet. Group of answer choices String Parameter SwitchParameter Required Parameter Positional ParameterIn order for a player to navigate your game, you will need to develop a function or functions using Python script. Your function or functions should do the following: Show the player the different commands they can enter (such as “go North”, “go West”, and “get [item Name]”). Show the player’s status by identifying the room they are currently in, showing a list of their inventory of items, and displaying the item in their current room. You could make these separate functions or part of a single function, depending on how you prefer to organize your code. Sample function showing the goal of the game and move commands def show_instructions(): #print a main menu and the commands print("Dragon Text Adventure Game") print("Collect 6 items to win the game, or be eaten by the dragon.") print("Move commands: go South, go North, go East, go West") print("Add to Inventory: get 'item name'") The blue image is an example of how the code should look.
