So I have a board game and the user is expected to enter the size of the board 3,4,5 ...will be 3x3, 4x4, 5x5, etc...
所以我有一个棋盘游戏,用户需要输入3,4,5的大小...将是3x3,4x4,5x5等...
Here:
board: .word 0:100 # declare a board of size 100 and make ints '0' , O = 1, X = 2
As you can see, this is static declaration...I need to somehow make an array the SIZE of the user input found in t0 for example...
正如你所看到的,这是静态声明...我需要以某种方式使数组成为在t0中找到的用户输入的SIZE,例如......

It sounds like you need to allocate some memory on the heap. The MARS emulator syscall for that is $v0 = 9, $a0 = number of bytes to allocate, returns address of allocated memory in $v0. Source: MIPS syscall functions available in MARS
听起来你需要在堆上分配一些内存。 MARS模拟器系统调用是$ v0 = 9,$ a0 =要分配的字节数,返回$ v0中分配的内存的地址。资料来源:MARS提供的MIPS系统调用功能
So your steps would be:
所以你的步骤将是:
- Get the array size from the user
- Square it
- Make syscall 9 with the size you calculated
从用户获取数组大小
使用您计算的大小制作系统调用9
