Expert Solution & Answer
Chapter 2.11, Problem 2.32CP
Explanation of Solution
Comments in Java:
A comment is used to document the program for better understanding of the program. The compiler treats the comment as a white space and ignores it during execution of the program.
Types of comments:
- Single line comment
- Multiline comment
- Documentation comment.
Single Line comment:
If the compiler encounters a single line comment (//), then it ignores the words up to the end of the line.
Syntax:
Single line comment:
//Java
Multiline comment:
If the compiler encounters a multiline comment (/* ...

Can you provide line by line explination using comments, what each line of code is doing?
In programming, comments can be used for what?
(A) For disabling some lines
(B) For separating different parts of the programs
(c) For specifying the objective of code
D) All of these choices
All programs must include introductory comments as well as comments all throughout the program. The introductory comment should include your name, the class name with section (e.g. CS 101 -24900), the program name, and a brief description of the program.
No need for pseudocode anymore!
Write your program in C++ with Visual Studio, or an online compiler - compile, and execute it.
For visual studio users;
Don't forget to use the system ("pause") before the "return" statement at the end of your program.
Program:
The annual fee of inflation is the rate at which money loses its value. For example, if the annual rate of inflation is 3.0 percent, then in one year it will cost $1,030 to buy the goods that would have been purchased for $1000 today.
Put another way, a year from now $1,000 will only buy 1/1.03 * $1,000, or $970.87, worth of goods. Two years from now, $1,000 will only buy only 1/1.03 of $970.87, or 942.59 worth of goods.

- I need three examples of code with comments when it's appropriate to use a comment.arrow_forward4arrow_forwardwhat is the purpose of writing comments and documentation in your source code? -you and others can understand what you are doing. -the compiler can interpret your code. -the program can interpret the algorithm correctly -the program will run more efficiently.arrow_forward
- 1. What refers to the structure of a program and the rules about that structure? 2. What statement is used to describes what’s going on inside a program so that a person looking at the source code does not have a hard time figuring it out.arrow_forwardLab Scenario: In this assignment, you will design a simple program to calculate a high school student's letter grade according to a specific grading chart based on their average test score. The program asks for a student's basic information such as the first name and last name, and the score recorded for the student's last four tests. It then calculates the average test score from the given data and assigns a letter grade. The purpose of this assignment is to gain experience in Python’s sequences, conditional. structures, and while loops.arrow_forwardFor this lab, you will be doing the following in C#: 1) Create a Home form with buttons that when clicked, will open the Account, Email, and eventually the Contact forms. The Account form should be opened in "View" mode. 2) Add code to the Login form so the Account form opens when the user clicks "Create New Account". The Account form should be opened in "Modify" mode. 3) Add code to the Login form that validates the user input before allowing the user the access the Home form. For now, just verify the user enters "user1" and "12345" for the username and password respectively.arrow_forward

For visual studio users; Don't forget to use the system ("pause") before the "return" statement at the end of your program. Pseudocodes are not required for your programs anymore. You can write it if it helps you with your programs, but no need to turn it in. Write a program with a loop that lets the user enter a series of integers, followed by -99 to signal the end of the series. After all the numbers have been entered, the program should display the largest and smallest numbers entered.
