模拟实现strcmp

#include<stdio.h>#include<stdlib.h>#include<assert.h>int my_strcmp(const char *arr1, const char *arr2){    while (*arr1 == *arr2)    {        if (*arr1 == '\0')            return 0;        arr1++;        arr2++;    }    return *arr1 - *arr2;}int main(){    char *arr1 = "acef";    char *arr2 = "aced";    int ret = my_strcmp(arr1, arr2);    printf("%d\n", ret);    system("pause");    return 0;}
