[solved] – Question 94916
Problem Statement:
Take user input for 2 numbers (num1 and num2). Write a program to perform the following operations:
Add = num1 + num2
Subtract = num1 – num2
Divide = num1 / num2
Modulus = num1 / num2
Multiply = num1 * num2
Find the greater of the 2 numbers, unless both numbers are equal (where you can display “numbers are equal”).
Note:
If a user enters a non-numeric entry (for any of the 2 numbers), exit the program with a message “Incorrect input, program exiting!!” displayed on screen.
The program should be able to accept any (both whole number and/or decimal, positive, negative etc.) numeric entries.
If one or more operations are not (mathematically) possible on the 2 numbers (e.g. 0/0), display a message, on screen, for the operation/operation(s), e.g. “Division – Operation not possible.”

Write a Person class with an instance variable age , and a constructor that takes an integer,initialAge , as a parameter. The constructor must assign initialAge to age after confirming the argument passed as initialAge is not negative; if a negative argument is passed as initialAge, the constructor should set age to 0 and print Age is not valid, setting age to 0.. In addition, you must write the following instance methods:
yearPasses() should increase the age instance variable by 1.
amIOld() should perform the following conditional actions:
If age<13, print You are young..
If age>=13 and age<18, print You are a teenager..
Otherwise, print You are old.

For the relations s and r in your study manual of our chapter 2 (i.e., joining two relations),
suppose we type a collection of relational algebra queries, and get the following results.
A B C D E
A 2 a 10 B
b 2 a 10 b
Please explain how this happened? If you think this result could happen in practice, please write the
corresponding relational algebra queries; otherwise, please explain why.

• void loadFile(string) – Given a filename, create the corresponding maze. Print the
following message to cout: “Loading level file <level>”, where <level> is replaced
by the filename. You need to populate two arrays: char** map and Entity** entities.
NOTE: if the file cannot be read, throw a FileException. If the maze dimensions given
on the first line of the level text file do not correspond to the provided map, thow a
MapException. Finally, when using pointers, throw NullPointerException where appropriate.
NullPointerException is a lot more informative than a segmentation fault, and
will help you debug your program
void draw() – Draw the map on the screen (cout). Note: the map array provides information
about walls and floors; you must combine this information with the list of entities
stored in the entities array.

[solved] – Question 95102
Write an application for the Summerdale Condo Sales office; the program determines the price of a condominium. Ask the user to choose 1 for park view, 2 for golf course view, or 3 for lake view. The output is the name of the chosen view as well as the price of the condo. Park view condos are $150,000, condos with golf course views are $170,000, and condos with lake views are $210,000. If the user enters an invalid code, set the price to 0.
Add a prompt to the CondoSales application to ask the user to specify a (1) garage or a (2) parking space, but only if the view selection is valid. Add $5,000 to the price of any condo with a garage. If the parking value is invalid, display an appropriate message and assume that the price is for a condo with no garage.
