User inputA feature in programming languages that allows users to provide the inputs for a program.
PromptA symbol or some text from a program indicating that it is waiting for an input from the user.
TestThe process of finding how well your code works by providing different inputs to the program.
ReusabilityQuality of the code that allows it to be reused.
Logical ErrorA logical error is a bug in a program that causes it to produce wrong or unintended result. However, the program compiles and runs without showing an error on the console.
Example: divided by ZERO, when an integer is divided by ZERO then it will compile successfully but at runtime, it will throw an error.
Syntax errorSyntax errors are mistakes that a developer/user can do while writing the code.
Example: System.out.Print(“Good morning!”) - In this line of code, alphabet p in print() has been capitalized, resulting in a syntax error.
shapeSize()shapeSize() method is used to fix the size of the turtle.
shape()shape() method is used change the shape of the turtle.
