arrays - MIPS help (convert from c++) - 初始化一个整数数组并计算最大值

Question

我需要帮助将此 C++ 代码转换为 MIPS 汇编语言。

int arr[10];
int min = 10000;
int max = -10000;
for (int i=0; i<10; i++)
    cin >> arr[i];

for (int i=0; i<10; i++) {
    if (arr[i] < min)
        min = arr[i];
    if (arr[i] > max)
        max = arr[i];
}

Answer 1

这些是用于处理器 32 的程序，它计算整数数组中的最大值和最小值，用户插入它的大小和元素

[#------Data segment-------
.data
arr1: .word 0       #array "A"
str: .byte 0x0A 0x0 # to make new line
hello: .asciiz " \t\t\t \t \t ---welcome---\n \t\t\t\t\t Name: Ahmed Kattash \t\t\t\t\t Number=0014 \n\t\t\t\t\t class 14\n this a program an array and a number from the user and we have three choice:\n 1-return a max element in the array\n 2-return  a min element in the array\n 3- show an error message if we entered a number unlike 1 or 2 \n"
str1: .asciiz " put the size of the array  : "
str2: .asciiz " insert elements of array : \n"
str3: .asciiz "Select achoice \n  press 1 to get max of array \n press 2 to get min of array "
str4: .asciiz " The max element of an array Max =   "
str5: .asciiz "The min element of an array Min =   "
str6: .asciiz "Your choice is worong please  try again \n  "
str7: .asciiz "\t\t\t\t thanks for using our program\n\n\n"
