C实现猜数字

一、概述

　　案例：使用C语言实现猜数字的功能。控制台会提是“大了”，“小了”，“猜对了”

　　目的：记录C的学习过程，并无其他实际含义

二、示例代码

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32

#include <iostream> #include <stdio.h> #include <stdlib.h> #include <time.h>     using namespace std;   int main(int argc, char const *argv[]) {     /* code */     srand(time(NULL));//随机数种子     int n = 0;     int num = rand()%100;//生成随机数字     cout << "rand num is "<< num<<endl;     for(;;){         cout<< "please input num:"<<endl;         scanf("%d",&n);         if(n<num){             cout << "Is too litter"<<endl;         }else if(n>num){             cout << "Is too biger"<<endl;         }else{             cout << "Is very good"<<endl;             break;         }         }     cout << "I am is "<< num<<endl;     return 0; }
