前言:  
位运算符是用来对二进制位进行操作的  
c语言中有6种位运算符:

本篇文章我们只讲左移和右移运算符,其他的会陆续在其他篇讲述

## **左移:** ##

## 右移: ##

## ** code：** ##

#include <iostream>
    
    int main()
    {
    	 auto i = 11;		//2进制: 1011 ,10进制:11
    	 i = i << 1;		//左移1位
    	 std::cout << i;	//2进制: 10110 ,10进制:22
    	 i = i << 1;		//继续左移1位
    	 std::cout << i;	//2进制: 101100 ,10进制:44
    
    	 auto i2 = 11;	
    	 i2 = i2 >> 1;		//右移
    	 std::cout << i2;	//2进制: 101 ,10进制:5
    	 i2 = i2 >> 1;		//继续右移一位
    	 std::cout << i2;	//2进制: 10 , 10进制:2
    
    	 system("pause");
    }

纯手写的 ,字有点丑,但是我感觉很详细简单了
