Program Plan Intro

Recursive method:

A method which is called again and again by itself is called as recursive method. With the help of recursive method, it is possible to solve certain problems more quickly and easily.

Base case: The recursion method contains a base case which is used to halt the recursion.

Recursive call: When the function itself calls the same function is called as recursive call.

“displayTriangles ()” method:

The “displayTriangles ()” method is used to display triangles by creating a triangle using “Polygon triangle = new Polygon ()” statement.

This function get all the points using “getPoints ()” function.

This method is a recursive method which contains base case and recursive call.

In this method, the base case is present in the “if” statement.

“if (order == 0)”

The command should also be placed in the history buffer as the next command. Whentheuserentersasingle!followedbyanintegerN,theNthcommandin the history is executed. In the example above, if the user entered the command: Osh> ! 3 The ‘ps’ command should be executed and echoed on the user’s screen. The command should also be placed in the history buffer as the next command. Error handling: The program should also manage basic error handling. For example, if there are no commands in the history, entering !! should result in a message “No commands in history.” Also, if there is no command corresponding to the number entered with the single !, the program should output "No such command in history."
