Question

Write a MIPS program that asks the user for 2 numbers. Output the sum of the 2 numbers. The difference between the 2 numbers (num1-num2) and (num2-num1)

The value that is 305 more than the 1st number.

The value that is 305 less than the 2nd number

Answer 1

MIPS Program to get two Numbers and Output the sum, the difference between two number (num1-num2) and (num2-num1) :

.data  #start of data segment
   # defining prompt message to be displayed.
   prompt1: .asciiz "Enter First Number " 
   prompt2: .asciiz "Enter Second Number "
   result_prompt1: .asciiz "\nThe sum of two number is "
   result_prompt2: .asciiz "\nThe difference (num1 - num2) is "
   result_prompt3: .asciiz "\nThe difference  (num2 - num1) is "
   
.text  # start of code segment
  main: #main
    
    li $v0,4 # this instruction is used to print string
    la $a0,prompt1 # preparing string to be displayed.
    syscall # issue system call to display string
    
    li $v0,5 #this instruction is used to get integer input.
    syscall  #issue system call to get user input.
    move $t0,$v0 #move entered value to register $t0
    
    li $v0,4 # this instruction is used to print string
    la $a0,prompt2 # preparing string to be displayed.
    syscall # issue system call to display string
    
    li $v0,5 #this instruction is used to get integer input.
    syscall #issue system call to get user input.
    move $t1,$v0 #move entered value to register $t1
    
    add $s0,$t0,$t1 # add to entered values and save result in $s0 register
    li $v0,4  # this instruction is used to print string
    la $a0,result_prompt1 # preparing string to be displayed.
    syscall # issue system call to display string
    li $v0,1 #prepare to display variable value
    move $a0,$s0 # move addition result to $a0
    syscall #issue system call
    
    sub $s1,$t0,$t1 # substract two values entered by user (num1-num2) and store in register $s1
    li $v0,4  # this instruction is used to print string
    la $a0,result_prompt2 # preparing string to be displayed.
    syscall # issue system call to display message
    li $v0,1 # prepare to display variable value
    move $a0,$s1 # move substraction result to $a0
    syscall # issue system call
    
    sub $s2,$t1,$t0 # substract two values entered by user (num2-num1) and store in register $s2
    li $v0,4  # this instruction is used to print string
    la $a0,result_prompt3 # preparing string to be displayed.
    syscall # issue system call to display message
    li $v0,1 # prepare to display variable value
    move $a0,$s2 # move substraction result to $a0
    syscall # issue system call
