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
#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; }
