CSE/EEE230 Assignment4

Due Date

Thursday, January 24th, 5pm

Important: This is an individual assignment. Please do not collaborate.

It must be submitted on-line (Blackboard).

No late assignment will be accepted

Minimal Submitted Files

You are required to turn in the following source file:

assignment4.s

Objectives:

-write assembly language programs to:

-perform decision making using branch instructions.

-use syscall operations to display integers and strings on the console window

-use syscall operations to read integers from the keyboard.

Assignment Description:

Write a MIPS assembly language program that reads in a sales type (1 or 2) and an amount of some sales.

If 0 or a negative integer is entered,

then the program should print out "No commission for the sales. ", and exit.

Otherwise, if a sale type is 1, and the amount is less than 10000 then the commission number will be 2, otherwise, it will be 4.

If a sale type is not 1 (i.e., 2), and the amount is less than 10000 then the commission number will be 3, otherwise, it will be 5.

After getting a commission number, it should compute the total commission that is computed by

totalCommission = (totalSales/1000)*commissionNum

then it should print out the total commission, along with its sales amount.

Name your source code file Assignment4.s.

The following shows how it looks like in a C program:

int salesType;

int commissionNum;

int totalSales;

int totalCommission;

printf("What is your sales type (1 or 2)? ");

//read an integer from a user input and store it in salesType

scanf("%d", &salesType);

printf("How much was the sales? ");

//read an integer from a user input and store it in totalSales

scanf("%d", &totalSales);

if (totalSales <= 0)

{

printf("No commission for the sales. ");

}

else

{

if (salesType == 1)

{

if (totalSales < 10000)

commissionNum = 2;

else

commissionNum = 4;

}

else

{

if (totalSales < 10000)

commissionNum = 3;

else

commissionNum = 5;

}

//compute its total commission

totalCommission = (totalSales/1000)*commissionNum;

//print out the total commission along with its sales

printf("Your total commission is %d for the sales of %d ", totalCommission, totalSales);

} //end of else

Here is a sample output (user input is in bold):

What is your sales type (1 or 2)?

1

How much was the sales?

12000

Your total commission is 48 for the sales of 12000

-----------------------------------------------

Here is another sample output (user input is in bold):

What is your sales type (1 or 2)?

2

How much was the sales?

1400

Your total commission is 3 for the sales of 1400

-----------------------------------------------

Here is another sample output (user input is in bold):

What is your sales type (1 or 2)?

1

How much was the sales?

0

No commission for the sales.

-----------------------------------------------
