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.
.data prompt2: .asciiz "Please enter value: " array1: .space 40 array2: .space 40 buffer: .space 4 .text main: #Prints the prompt2 string li $v0, 4 la $a0, prompt2 syscall #reads one integer from user and saves in t0 li $v0, 5 la $t0, buffer syscall li $v0, 1 li $t0, 5 # $integer to print syscall exitProgram: li $v0, 10 # system call to syscall # terminate program 2 Answers
This is how I will write a program to get an integer input and to print it out
.data text: .asciiz "Enter a number: " .text main: # Printing out the text li $v0, 4 la $a0, text syscall # Getting user input li $v0, 5 syscall # Moving the integer input to another register move $t0, $v0 # Printing out the number li $v0, 1 move $a0, $t0 syscall # End Program li $v0, 10 syscall #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.
