Homework Assignment $4-$B

For this Assignment you will attach ONE file, your program file $($the $.$cpp file$).$ DO NOT cut and paste your

code into the Add Comments section of the Assignment or email your program, your program will NOT be

graded and you will receive a zero for the assignment.

If program does not compile you will automatically lose $-10.$

PROBLEM: The Drawing Program. $(20$ pts$)$

Write a program that will draw a rectangle given a width and a length using asterisks.

You will display the following welcome message:

Welcome to Rectangle Draw It$!!$

$^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^$

You must validate the input for the width and the length. Do not allow any non$-$zero or negative values to be

entered. If an invalid value is entered, you must continue to ask the user to enter a value until a valid value is

entered.

Your program must use loops to draw the rectangle made up of asterisks on the screen. Do not allow a

rectangle larger than $20$ asterisks wide or $20$ asterisks long to be generated. Use the number $99$ to exit.

The program should continue to loop until the user is ready to quit. $($Hint: After you have your program

running, completely enclose your program in a do$/$while loop that only exits if the user chooses to quit$).$

Input Validation: Only values greater than zero may be entered. Zero is not a valid value. If the user does

not enter a valid value, display an error message and ask the user to enter the value again until a valid value

is entered. Valid values for the rectangle are integer values from $1$ to $20,$ inclusive.

SAMPLE OUTPUT:

PARTIAL PSEUDO$-$CODE:

A$)$ Declare necessary variables for user input

B$)$ Display welcome screen

C$)$ Ask the user for the length of the rectangle

D$)$ Read in the length

E$)$ Validate user input $($must input $1$ through $20($inclusive$)$ or $99),$ loop if value is invalid

CONSTRAINTS:

$$ The program MUST be written as one main program $($NO Functions$).($Automatic $-10$ if not one main

function$)$

$$ You must use: int main$()$

$$ You can only use the following libraries and

$$ No Arrays or Vectors

$$ The program must use integers. $(2$ pts$)$

$$ The program must use local variables. $(2$ pts$)$

$$ Input Validation: All input must be validated $($Please see specification in description above$)(4$ pts$)$

$$ The program must use loops. $(4$ pts$)$

$$ Output must be formatted properly and correct. $(3$ pts$)$

$$ Include a comment at the beginning of the program stating the purpose of the program, your name,

the date, and your class $(1$pt is for code organization and use of whitespace$).(3$ pts$)$

$$ Algorithm or Pseudo Code $($as an outline$)$: At the beginning or end or your program write the

algorithm or pseudo code as a multi$-$line comment. $(2$ pts$)$
