如何使用 MARS/SPIM 系统调用在同一行打印数字和字符串？

Question

最近，我正在做作业，并且正在努力在同一行上打印变量和字符串。我想问一下如何在 MIPS 中将它们打印在同一行上？

我目前的成绩：

Please enter your nickname: Harry
Please enter your surname: Chan
Harry
Chan
How old are you? 20
You are 20
 years old.

我想要的：

Please enter your nickname: Harry
Please enter your surname: Chan
Harry
Chan
How old are you? 20
You are 20 years old.

MIPS 代码：

.data

question1: .asciiz "Please enter your nickname: "
question2: .asciiz "Please enter your surname: "
question3: .asciiz "How old are you? "
buffer1: .space 60
buffer2: .space 60
buffer3: .space 60
str1: .asciiz "You are "
str2: .asciiz " years old."

我同学的回答：

    #print out question 3 and store input

        li $v0, 4
        la $a0, question3 

        syscall

        li $v0, 5
        syscall

        move $t0, $v0

    #print out str 1, str2 and answer

        li $v0, 4
        la $a0, str1
        syscall

        li $v0, 1
        move $a0, $t0
        syscall

        li $v0, 4
        la $a0, str2
        syscall
