Question

Design, write, and test a program in MIPS which requests and reads two integer values from the user, multiply the values together, and then outputs the results.

Answer 1

//Tested on Mars simulator

//user should have knowledge about register and instruction set

/************multiplication.asm*************/

.data
    prompt: .asciiz "please Enter first number:"
    prompt1: .asciiz "Please Enter second number:"
    message: .asciiz "Multiplication is:"

.text
     #Prompt the user to enter first number
     li $v0,4 #4 for string
     la $a0,prompt
     syscall

     #Storing first number
     li $v0,5 #5 for integer
     syscall    

     #Store the result in $t0
     move $t0,$v0
   
     #Prompt the user to enter Second number
     li $v0,4 #4 for string
     la $a0,prompt1
     syscall
   
     #Storing second number
     li $v0,5 #5 for integer
     syscall
     #Store the result in $t1
     move $t1,$v0
   
     #multiply both number and storing result into $t2
     mul $t2,$t1,$t0
   
     #displaying message
     li $v0,4
     la $a0, message
     syscall
   
    #printing multiplication
    li $v0,1
    move $a0,$t2
    syscall

/***************output***********/

please Enter first number:10
Please Enter second number:3
Multiplication is:30
