Question

我可以找到最大值，但是当找到最小值时，我遇到了麻烦，我的最大值找到了最大值，但是无论如何我的最小值始终打印为0，我似乎无法找出是什么我的代码有问题，有人看到我的代码有缺陷吗？

例如：

我输入5个整数

5 10 15 20 25

数组：5,10,15,20,25

最小值：0 最多：25

.text
    .globl main

main:
    la $a0, ask             #ask user for integer thats going to be the size of the array
    li $v0, 4
    syscall

    li $v0, 5               #store that int
    syscall
    move $t1,$v0            #size of my array stored in $t1

    la $t0, array           #load address of our array
    li $t2, 0               #counter = 0
    lw $t3,($t0)            #initialize min = array[0]
    lw $t4,($t0)            #initialize max = array[0]


while:
    la $a0, intask          #ask user for integer
    li $v0, 4
    syscall

    li $v0, 5               #store that int
    syscall
    sw $v0, ($t0)           #store that int in the array


end:    add $t0, $t0, 4         #increment the array to the next index
    add $t2, $t2, 1         #increment the counter by 1
    blt $t2, $t1,while      #branch to while if counter < size of array

您正在将$t3（用于存储最小值）初始化为array[0]，然后再将任何值存储在array中，因此$t3最终被初始化为0。

如果在将$t3输入值之后将array[0]初始化为array ，应该没问题。

如何在数组MIPS中查找最小值和最大值
