Question
Use the program below:

Modify the program that will test whether or not the expression evaluates to a negative or positive number.

This is in MIPS Assembly Language

Sample OUTPUT:

The output is 14

output is positive. THIS DOES NOT SHOW IN CODE

 
 
 
#Evaluate the expression: 4x^2 - 8x + 2
.data
prompt: .asciiz "Enter an input for x to evaluate 4x^2 - 8x + 2: "
output: .asciiz "The output is "
.text
main:
li$v0,4#output the prompt for user
la$a0,prompt
syscall
 
li$v0,5#input the number and save it to $s0
syscall
move $s0,$v0
 
#square the input
#lw$t0, ($s0)
mul$t0, $s0, $s0
#multiply by 4
mul$t0, $t0, 4
#multiply input by -8
#lw $t2, ($s0)
mul $t2, $s0, -8
#add it all
add$t0, $t0, $t2
add$t0, $t0, 2
 
li$v0,4#print the output label
la$a0,output
syscall
 
li$v0,1#output the number that was entered
move$a0,$t0#could also use lw $a0, $s0. Pseudo code
syscall
 
li$v0, 0xB
#print newline, 0xB = 11 
#which is the system call to print a single character   
la$a0, 0xA#0xA is the newline char
syscall
 
li$v0,10#exit program
syscall
