使用do while ,while的猜数游戏

#include<stdio.h>#include<stdlib.h>#include<time.h>main(){    int a,guess,ret,cishu;    char reply;    srand(time(NULL));    do{        cishu=0;        a=rand()%10+1;        do{        printf("请猜一个数:");        ret=scanf("%d",&guess);        while(ret!=1){            fflush(stdin);            printf("输入的必须是数字，请重新输入:");            ret=scanf("%d",&guess);        }        cishu++;        if(guess<a){            printf("too samll!\n\n");        }else if(guess>a){            printf("too big!\n\n");        }else{            printf("right!\n");        }        }while(guess!=a&&cishu<10);        printf("尝试次数:%d\n\n",cishu);        printf("你还想继续吗？:");        scanf(" %c",&reply);        fflush(stdin);        if(reply=='n'||reply=='N'){            break;        }    }while(reply!='y'||reply!='Y');}
