mips语言判断闰年

在 MIPS 语言中，可以使用以下代码来判断一个年份是否为闰年：

.data
prompt: .asciiz "Enter a year: "
leapYear: .asciiz "The year is a leap year."
notLeapYear: .asciiz "The year is not a leap year."

.text
.globl main

main:
    # Prompt user to enter a year
    li $v0, 4
    la $a0, prompt
    syscall
    
    # Read the year from user input
    li $v0, 5
    syscall
    move $t0, $v0
    
    # Check if it is a leap year
    li $t1, 4       # remainder for divisible by 4
    li $t2, 100     # remainder for divisible by 100
    li $t3, 400     # remainder for divisible by 400
    
    div $t0, $t1
    mfhi $t4        # check remainder for divisible by 4
    
    div $t0, $t2
    mfhi $t5        # check remainder for divisible by 100
    
    div $t0, $t3
    mfhi $t6        # check remainder for divisible by 400
    
    beqz $t4, not_leap_year         # if not divisible by 4, go to not_leap_year
    beqz $t5, not_leap_year         # if divisible by 4 but divisible by 100, go to not_leap_year
    beqz $t6, leap_year             # if divisible by 4 and 100 but divisible by 400, go to leap_year
    
not_leap_year:
    li $v0, 4
    la $a0, notLeapYear
    syscall
    j end
    
leap_year:
    li $v0, 4
    la $a0, leapYear
    syscall
    
end:
    li $v0, 10      # exit program
    syscall

该程序会要求用户输入一个年份，然后通过对年份进行取余运算来判断是否为闰年。如果是闰年，程序会输出"The year is a leap year."，否则输出"The year is not a leap year."。
