strcmp实现

# include <stdio.h># include <string.h># include <assert.h># include <stdlib.h>int my_strcmp(char *str1, char *str2){assert(str1!=0 && str2!=0);while(*str1 == *str2 && (*str1 != '\0')){str1++;str2++;}if (*str1 > *str2)return 1;else return 0; return -1;}int main(void){char s1[] = "cbc";char s2[] = "db";printf("%d\n", my_strcmp(s1, s2));return 0;}
