Manipulate refers to the process of changing or altering data in a program. It involves modifying variables, arrays, or objects to achieve a desired outcome.
An array is a collection of elements of the same type stored in contiguous memory locations. It can be manipulated by accessing and modifying individual elements.
An object is an instance of a class that encapsulates both data (attributes) and behavior (methods). It can be manipulated by invoking its methods or accessing/modifying its attributes.
