Question

Create a MIPS program that will "hard code an integer" (meaning declared in .data) and read in another integer, multiply them together, and print out the results.

Answer 1

Used MARS 4.5 Version

code below ::

.data
var1: .word 3 #A hard code integer declared in .data using word
prompt: .asciiz "Enter your number"
.text

   addi $s1,$zero,0 #clear $s1 register
   lw $s1,var1    #load contents of Ram location into register $s1
  
   #to display the prompt
   li $v0,4 #used for display
   la $a0,prompt #$a0 used for argument to be displayed
   syscall
  
   li $v0,5   #get input from the user (read in user input)
   syscall
   move $t0,$v0   #move the input integer to $t0
  
  
   mul $t0,$s1,$t0      #multiply contents of $s1 and $t0 and store it in $t0
  
   #display the multiplied value
   li $v0,1
   add $a0,$zero,$t0
   syscall

OUTPUT:

Execute the code by pressing F3 or compiling.
