简单的随机数应用

有兴趣的可以玩玩

#include <stdio.h>#include <stdlib.h>#include <time.h>#define N 4/*随机抽N个数*/#define MAX 50//最大尝试数目int main(){int i;int count;//次数int s_passw[N+1];void detect(int[],int);srand(time(NULL));for(i=0;i<N;i++){s_passw[i]=rand()%10;//得到随机数}printf("****\n");printf("自信的你想要猜几次呢: ");scanf("%d",&count);//输入次数while(1){if(count>MAX){printf("太多了，少一点: ");scanf("%d",&count);//输入次数}elsebreak;}detect(s_passw,count);return 0;}void get_number(char &a,int &b)//类型转换{b=a-'0';}void detect(int right[],int count){int i,j,num;int times=0,guess_i[N+1];char guess_c[N+1];for(num=0;num<count;num++)//机会{times=0;printf("第%d次机会: ",num+1);scanf("%s",guess_c);//得到值for(i=0;i<N;i++){get_number(guess_c[i],guess_i[i]);}for(j=0;j<N;j++)//检查跟正确值的差异{if(guess_i[j]==right[j]){printf("1");times++;}elseprintf("0");}printf("\n");if(times==N)//4个正确{printf("Congratulations!\n");break;}}if(times!=N)//一直不正确{printf("Sorry,you haven't guess the right number!\nThe correct answer is：");for(j=0;j<N;j++){printf("%d",right[j]);}}}
