我正在处理一个应该接受来自用户的输入（数字1-9）的程序，然后使用该输入来打印已完成的MIPS指令（1 = add，2 = addi ，3 =或等）。
这样的一个例子是用户输入数字1，程序输出＆＃34; add $t2, $t0, $t1＆＃34;。用户输入数字2，程序输出＆＃34; addi $t3, $t2, 100＆＃34; （寄存器是连续的和链接的。）
因此，如上所述，程序的一个功能是在用户输入数字时迭代寄存器$t0-$t9。我认为打印这些寄存器及其相关操作码的最佳方法是将它们放入一个数组中并循环遍历它们。但是，我无法找出MIPS是否/如何打印出字符串数组（是的，我看到另一个stackoverflow帖子提出同样的问题，但我不太明白答案，因为它＆＃39;用C）写的。
我真的很感激人们能给予的任何帮助！
这是我的代码的相关部分（我知道它并不多，对不起）：
