Expert Solution & Answer
Chapter 7, Problem 1D
a)
Explanation of Solution
Simple decision:
- In python, decisions can be implemented using “if” statements.
- Python handles the following type of decisions,
- Simple decision
- Two-way decision
- Multi-way decision
- Simple decisions can be implemented by a simple “if” statement.
- Example:
#Initialize the variable
a=1
#Check the condition using “if” statement
if (
b)
Explanation of Solution
Two-way decision:
- In python, decisions can be implemented using “if” statements.
- Python handles the following type of decisions,
- Simple decision
- Two-way decision
- Multi-way decision
- Two-way decisions can be implemented by “if-else” statement.
- Example:
#Initialize the variables
a=5
b=3
#Check the condition using “if” statement
if(a<b):
�...
c)
Explanation of Solution
Multi-way decision:
- In python, decisions can be implemented using “if” statements.
- Python handles the following type of decisions,
- Simple decision
- Two-way decision
- Multi-way decision
- Multi-way decision can be implemented by “if-elif-else”, and nested “if-else” statements.
- Example:
#Initialize the variables
a=5
b=3
c=6
#Check the condition using “if” statement
if(a<b && a<c):
#Print “a” value
print(a)
#Check the condition using “elif” statement
elif(b<c):

Consider the following class declaration.
public class Sample
{
private int a;
private double b;
public Sample (int x, double y)
{
