strcmp()返回C中的值

int strcmp(const char *str1, const char *str2);

#include<stdio.h>
#include<string.h>

int main() {
    char str1[] = "hello";
    char str2[] = "world";
    char str3[] = "hello";

    int result1 = strcmp(str1, str2);
    int result2 = strcmp(str1, str3);

    printf("str1和str2的比较结果：%d\n", result1);
    printf("str1和str3的比较结果：%d\n", result2);

    return 0;
}

str1和str2的比较结果：-1
str1和str3的比较结果：0
