and when I run this code it said syntax error at line 13 which is li $v0,4
can someone tell me what is happening?
I want to input an integer and have it be expressed in both binary and hex. Then I want to move bits 12, 13, 14, and 15 to the least significant bits of $a0, and have the output be expressed as a binary and hex. Here's my program:
.data
enter: .asciiz "Please enter your integer:\n"
binaryI: .asciiz "\nHere is the input in binary: "
hexI: .asciiz "\n\nHere is the input in hexadecimal: "
binaryO: .asciiz "\n\nHere is the output in binary: "

For the integer 1006460, for example, the inputs and hex output work perfectly, but the binary output has an extra 5 at the end. The error I get is this:
Here is the output in binary: 0x000000055
What may have caused this extra 5 to be at the end of the output?
How silly of me. I should have deleted
li $v0, 1
add $a0, $0, $s0
syscall
from my code.
I am new in mips and i got this assignment that asks me to take 2 inputs from user and divide them and get a floating point output.
The problem is the output comes out like this 0.000000000, not the predicted output
this is my code
.data
str1: .asciiz "Enter a: "
str2: .asciiz "Enter b: "
str3: .asciiz " a/b = "

im trying find out substring and first occurrence indices. but something wrong. im comparing each element of pattern array and each element of string array until pointer reach to '\0'. whats the problem. algorithm is totaly wrong ?

I used your code for a similar project, in inner_loop you don't have a proper bne
I just put one bne and now it print just the string whit the substring..
