Chapter 10: Problem 13

A program creates 10 instances of the Coin class. How many _ _sideup attributes exist in memory?

Short Answer

Expert verified
Answer: 10

Step by step solution

01

Understanding instances and attributes

In object-oriented programming, an instance is created whenever a program creates a new object based on a defined class. In our exercise, we are creating 10 instances of the Coin class. Each instance will have its own attributes, which include _sideup in this case.
02

Counting the number of _sideup attributes

Since each of the 10 instances will have its own set of attributes, and _sideup is an attribute of each instance, there will be a total of 10 _sideup attributes existing in memory.
