Question

Write a mips assembly code program that ask the user to enter an integer value, and then print
the result of doubling that number.

Answer 1

.data

prompt1: .asciiz "Enter the first number: "

resultText: .asciiz "Your final result is: "

.text

.globl main

main:

#The following block of code is to pre-load the integer values representing the various instructions into registers for storage

li $t3, 1 #This is to load the immediate value of 1 into the temporary register $t3

li $t4, 2 #This is to load the immediate value of 2 into the temporary register $t4

li $t5, 3 #This is to load the immediate value of 3 into the temporary register $t5

#asking the user to provide the number

li $v0, 4 #command for printing a string

la $a0, prompt1 #loading the string to print into the argument to enable printing

syscall #executing the command

#the next block of code is for reading the first number provided by the user

li $v0, 5 #command for reading an integer

syscall #executing the command for reading an integer

move $t0, $v0 #moving the number read from the user input into the temporary register $t0

add $t6,$t0,$t0 #this adds the values stored in $t0 and $t1 and assigns them to the temporary register $t6

#The following line of code is to print the results of the computation above

li $v0,4 #this is the command for printing a string

la $a0,resultText #this loads the string to print into the argument $a0 for printing

syscall #executes the command

#the following line of code prints out the result of the addition computation

li $v0,1

la $a0, ($t6)

syscall

li $v0,10 #This is to terminate the program

Note: Plzzz don' t give dislike.....Plzzz comment if u have any problem i will try to resolve it.......
