Assembly Language Programs using QtSpim Project

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 checks if a customer is a member or not, and reads in their purchased amount, and gives discounts accordingly.

If a customer is a member and their purchased amount is less than or equal to 9

0

00, then the customer gets

1

0% discount, i.e., their payment will be their purchased amount * (0.9). If a customer is a member and their purchased amount is greater than

9000

, then the customer gets 10% discount and also a discount of 200, i.e., their payment will be their purchased amount * (0.9) – 200. If a customer is not a member, there is no discount.

Name your source code file Assignment4.s.

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

 int membership; int purchasedAmount; int payment =0; printf(“

Are you a store member? Enter 1 for a member, 0 for a non-member

\n”); //read an integer from a user input and store it in membership scanf(“%d”, &membership); if (membership !=0 && membership != 1) {   printf(“

Invalid Answer.

“); } else { printf(“

Enter your purchase amount in cents:

\n”); //read an integer from a user input and store it in purchasedAmount scanf(“%d”, &purchasedAmount);    if (membership == 1 && purchasedAmount <= 9000)   {      payment = purchasedAmount - purchasedAmount/10;   }   else if (membership == 1 && purchasedAmount > 9000)   {      payment = purchasedAmount – purchasedAmount/10 – 200;   }   else if (membership == 0)   {      payment = purchasedAmount;   }   //print out the payment   printf(“Your total payment is %d \n”, payment); } //end of else 

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