本文解释了在计算机科学中，如何通过1<<n进行左移操作，相当于乘以2的n次方，以及1>>n的右移操作，等效于除以2的n次方。通过实例说明了1<<(2-1)的左移过程，帮助读者掌握二进制位操作的基础概念。

<<左移

1<<n相当于乘以2的n次方(小于号 相反意思是放大 乘以2的n次方)

>>右移

1<<n相当于除以2的n次方

输入口味“2”。先做移位 1<<(2-1)，得二进制数 10 左移

在输入流情况下，它从右操作数（通常是一个输入流对象）中读取输入，并将结果存储到左操作数（通常是一个变量）中。- 在输出流情况下，它将右操作数（通常是变量或常量）的内容输出到左操作数（通常是一个输出流对象）中。- 在位运算情况下，它执行左移操作，将左操作数的位向左移动指定的位数，并将结果存储在左操作数中。例如，`x << 2;- 在位运算情况下，它执行右移操作，将左操作数的位向右移动指定的位数，并将结果存储在左操作数中。需要注意的是，<< 和 >> 运算符可以被重载，以实现用户自定义的输入和输出操作。

<<<<<<是左移运算符的意思，左移运算符是用来将一个数的各二进制位全部左移若干位,右补0。高位左移后溢出，舍弃。 例如： 将a的二进制数左移2位，右补0。若a=15，即二进制数00001111，左移2位得00111100，即十进制数60。 语法格式：需要移位的数字 << 移位的次数 例如： 3 << 2，则是将数字3左移2位。即00000011----->00001100(12); >>>>>>右移运算符

右移运算符>>(有符号)用来将一个数的各二进制位全部右移若干位.例如:a = a>>2,使a的各二进制位右移两位,移到右端的低位被舍弃,最高位则移入原来高位的值. （正数右移是正数，负数右移是负数）如:a = 00110111,则a>>2=00001101,b=11010011,则b>>2 = 11110100 右移一位相当于除2 取商,而且用右移实现除法比除法运算速度要快 左移运算符同上，末位补
