C语言问题，编写一个将C语言 变成 MIPS 汇编程序

Question

望各位帮忙看看，现在就想要答案，蟹蟹各位潜水专家，感谢解答，感谢回答，感谢解答。编写一个 MIPS 汇编程序，相当于这个 C 程序：在原有的基础上完成这个程序

# read a mark and print the corresponding UNSW grade

main:
    la   $a0, prompt    # printf("Enter a mark: ");
    li   $v0, 4
    syscall

    li   $v0, 5         # scanf("%d", mark);
    syscall

    la   $a0, fl        # printf("FL\n");
    li   $v0, 4
    syscall


    jr   $ra            # return

    .data
prompt:
    .asciiz "Enter a mark: "
fl:
    .asciiz "FL\n"
ps:
    .asciiz "PS\n"
cr:
    .asciiz "CR\n"
dn:
    .asciiz "DN\n"
hd:
    .asciiz "HD\n"
