Question

 project 5 functions calling functions

 white a program that determines if 3 numbers that are entered, by the user, are sides of a right triangle.

 remember any combination of numbers can be entered, 3 4 5, 5 4 3, 4 3 5... are all the same right triangle.

 you must have a function that does exponentiation,

 one that does input one that does output.

 and one that does the comparisons

 the main will be this code

 main:

    jal allwork

    li $v0,10

    syscall

 function allwork will call function input which will ask the user for a number,

 input will call function pow which will square the number (it must work with any exponent >=0)

 allwork will also call function check, which will check if it's a right triangle,

 and function print, which will output if it is a right triangle or not.

 some of these functions will be called more than once

 you will need the stack to manage the nested functions, and their return address'.

Answer 1

.data
stmt:    .asciiz "Enter a: "
stmt1:    .asciiz "Enter b: "
stmt2:    .asciiz "Enter c: "
stmt3:    .asciiz "The sides form a right angled triangle"
stmt4:    .asciiz "The sides doesn't form a right angled triangle"
.globl main
.text
main: jal allwork
exit:   li $v0,10
    syscall
   
allwork: jal input

input:       la   $a0, stmt       # load address of stmt for syscall
           li   $v0, 4           # specify Print String service
           syscall      
       li      $v0,5                   # get an integer from the user
           syscall
       # Store the a value in t0
        move    $t0,$v0
       
        la   $a0, stmt1       # load address of stmt for syscall
           li   $v0, 4           # specify Print String service
           syscall      
       li      $v0,5                   # get an integer from the user
           syscall
       # Store the a value in t0
        move    $t1,$v0
       
        la   $a0, stmt2       # load address of stmt for syscall
           li   $v0, 4           # specify Print String service
           syscall      
       li      $v0,5                   # get an integer from the user
           syscall
       # Store the a value in t0
        move    $t2,$v0
        j pow
       
pow:       mul $s0,$t0,$t0
        mul $s1,$t1,$t1
        mul $s2,$t2,$t2
        j check
check:       add $s3,$s0,$s1
        add $s4,$s2,$s1
        add $s5,$s0,$s2
       
        beq $s3,$s2,true
        beq $s4,$s0,true
        beq $s5,$s1,true
        j false
false:       la   $a0, stmt4      # load address of stmt for syscall
           li   $v0, 4           # specify Print String service
           syscall  
           j exit
true:         la   $a0, stmt3      # load address of stmt for syscall
           li   $v0, 4           # specify Print String service
           syscall  
       
       
        

Output:
