Chapter 4.13, Problem 4.42CP
Program Plan Intro
Enumeration:
Enumeration is a user-defined data type which consists of enumerators; the enumerators are used to represent integer constants.
- An enumeration can be defined by using the keyword “enum”.
- By default, the values of enumeration type are filled with “0” to “n” sequentially and those default values can be changed when declaring the enumeration.
Syntax:
Syntax to declare an enumerated data type is as follows,
enum type_name {identifier_1, identifier_2, identifier_3, … identifier_n};
In the above syntax,
- “enum” is the keyword used to declare an enumerator.
- “type_name” is the name of the enumeration.
- “identier_1” to “identifier_n” is the list of the identifiers declared in the enumerator.

Do not use regular expressions in your solution for this exercise. Write a program that checks to see if an input password is valid or not. In this exercise, a valid password has the following characteristics:
It contains at least eight characters.
It contains at most 12 characters.
It contains only alphabetic characters, digits and the underscore (‘_’) character.
It does not start with a digit.
It has a mix of upper-case and lower-case characters.
Your class must contain the following method: public static String checkPassword(String input)
This method receives a possible password as input and returns only the String“OK” if the password is valid. If the password is not valid then you can return the reason(s) for that as the return value. This is not a part of the requirements, however, and you don’t need to do that. You can simply return null for an invalid password.
8- Create an instance of the following class and call its methods.
class Exam{
int grade;
public:
void seta (int b) (grade=b; }
int geta () {return grade; }
9- When the word const is put before the variable definition, what does that mean?
10- How to concatenate two strings in C++ language?
C++
Declare Math class which has a function overloading. There are two
versions of add function. The first function has two parameters to
add it and function one has three to add it.

Design a class, pointType, that can store and process a point in the x-y plane. You should then perform operations on the point, such as showing the point, setting the coordinates of the point, printing the coordinates of the point, returning the x-coordinate, and returning the y-coordinate. Also, write a test program to test the various operations on the point.arrow_forward
- Assignment 4 - Car Maintenance This assignment will assess your understanding of void and value returning static methods. Your cousin owns an automotive maintenance shop that performs routine maintenance on cars. He has asked you to write a program that will provide a list of services (and their respective prices) to users and allow them to choose any, or all, services they would like and display the final price, including a 28% labor charge, a 9% markup if the car is an import, and an 8% sales tax. Task To accomplish the above, do the following: • Write the two methods outlined below. • Test your program and screenshot your successful test. carMaintenance method This method should accept the make of the car as a parameter (e.g., BMW, Ford, Ferrari, etc.).

Write a program that will help an elementary-school student learn multiplication. Use a Random object to produce two positive one-digit integers. The program should then prompt the user with a question, such as: How much is 6 times 7? The student then inputs the answer. Next, the program checks the student’s answer. If it is correct, display the message "Very good!" and ask another multiplication question. If the answer is wrong, display the message "No. Please try again." and let the student try the same question repeatedly until the student gets it right. A separate method should be used to generate each new question. This method should be called once when the app begins execution and each time the user answers the question correctly.arrow_forward
