Assignment Four

Obiectives:

A$.$ To create a design diagram

B$.$ To accept input into a program

C$.$ To use the Selection construct with nested selection

Assignment:

Part I

This assignment has a

bonus that is worth $5$ extra

points. If you have

completed the entire

assignment and your

program works as

expected, then $($and only

then$),$ feel free to do the

bonus that is on page $8.$

Copy the diagram shown below into a new word processing page. Fill it out. Save this as a Word file titled

Assignment$4$DesignDiagram.

Remember that the only variables on a design diagram are input and output variables. The process is a

simplified list of the steps of the program. Do not use bullets or numbering. Do use the correct variable

names when referring to them in the process portion.

Part II

Write a program called Assignment$4.$ The program will ask a user to enter two integers into variables called

number$1$ and number$2.$ The program then will show the user a menu that has five choices. These choices are

to calculate the addition, subtraction, division, and modulus of two numbers, and to quit the menu.

If the user chooses a number below $1$ or above $5,$ then your program will tell the user Invalid choice, Please

select $1-5.$ Allow the user to reenter the number. This is a separate if statement.

The program will then go into the nested if statements to do choice $1,2,3,4,$ or $5.$

Note: There will be only once chance to let the user re$-$enter. There is no loop.

If the user chooses $1,$ then your program will calculate the addition of the two numbers and display

the result. This is an if statement.

The formula is addNumbers $=$ number $1+$ number $2$

If the user chooses $2,$ then your program will calculate the subtraction of the second number from the

first number and display the result. This is an if else statement.

The formula is subtractNumbers $=$ number $1-$ number $2$
