有三个字符串，要求找出其中最大者

#include<stdio.h>#include<string.h>int main (){char str[3][20];char string[20];int i;for(i = 0;i < 3;i++){gets(str[i]);}if(strcmp(str[0],str[1]) > 0){strcpy(string,str[0]);}else{strcpy(string,str[1]);}if(strcmp(str[2],string) > 0){strcpy(string,str[2]);}printf("\n");printf("the largest string:\n");printf("%s\n",string);return 0;}
