使用Intel语法将汇编代码实现字符串比较，并将其嵌入到C或C++程序中。以下示例代码使用了“jne”和“loop”指令来比较字符串的每个字符。

section .data
    str1 db 'Hello World!',0
    str1len equ $-str1
    str2 db 'Hello',0
    str2len equ $-str2

section .text
    global _start

_start:
    ; load string pointers and lengths
    mov esi, str1
    mov edi, str2
    mov ecx, [str1len]
    cmp ecx, [str2len]
    jne .not_equal ; strings not equal if lengths differ

    ; compare string characters
    repe cmpsb
    je .equal ; strings are equal if zero flag is set

.not_equal:
    ; strings are not equal
    mov eax, 1 ; return 1 to indicate non-equality
    mov ebx, 0 ; return 0 as the exit code
    int 0x80

.equal:
    ; strings are equal
    mov eax, 0 ; return 0 to indicate equality
    mov ebx, 0 ; return 0 as the exit code
    int 0x80
