CS271- Assignment 3 Solved

Write and test a MASM program to perform the following tasks:

1.     Display the program title and programmer’s name.

2.     Get the user’s name, and greet the user.

3.     Display instructions for the user.

4.     Repeatedly prompt the user to enter a number.  Validate the user input to be in [-100, -1] (inclusive).  Count and accumulate the valid user numbers until a non-negative number is entered.  (The nonnegative number is discarded.)

5.     Calculate the (rounded integer) average of the negative numbers.

6.     Display:

i.              the number of negative numbers entered  (Note: if no negative numbers were entered, display a special message and skip to iv.)

ii.            the sum of negative numbers entered

iii.          the average, rounded to the nearest integer (e.g. -20.5 rounds to -20)

iv.          a parting message (with the user’s name)

 

Requirements:

1.     The main procedure must be modularized into commented logical sections (procedures are not required this time)

2.     The program must be fully documented.  This includes a complete header block for identification, description, etc., and a comment outline to explain each section of code.

3.     The lower limit should be defined as a constant.

4.     The usual requirements regarding documentation, readability, user-friendliness, etc., apply.

5.     Submit your text code file (.asm) to Canvas by the due date.  

 

Notes:

1.      There are no new concepts in this programming assignment.  It is given for extra practice, to keep MASM fresh in your mind while we study internal/external data representation.

2.      This is an integer program.  Even though it would make more sense to use floating-point computations, you are required to do this one with integers.

Welcome to the Integer Accumulator by Austin Miller 

What is your name? Caleb 

Hello, Caleb 

 

Please enter numbers in [-100, -1]. 

Enter a non-negative number when you are finished to see results. 

Enter number: -15 

Enter number: -100 Enter number: -36 

Enter number: -10 

Enter number: 0 

You entered 4 valid numbers. 

The sum of your valid numbers is -161 

The rounded average is -40 

Thank you for playing Integer Accumulator! It's been a pleasure to meet you, Caleb.

 

Extra-credit options (original definition must be fulfilled):

1.      Number the lines during user input.

2.      Calculate and display the average as a floating-point number, rounded to the nearest .001.

3.      Do something astoundingly creative.
