Reading and printing an integer in mips

Question

My program is suppose to read an integer and print it back to the user but every time it just prints 268501230 no matter what is entered. Any help would be appreciated.

Answer 1

#reads one integer from user and saves in t0
li $v0, 5
la $t0, buffer
syscall

That's not how syscall 5 works. The integer is returned in $v0, so the code ought to be something like:

li $v0,5
syscall
move $t0,$v0

---

li $v0, 1       
li $t0, 5       # $integer to print
syscall 

You're using the wrong register here as well. The integer to print should go into $a0, not $t0.

Here's a list of syscalls and the registers they use.
