C++使用按位右移/按位左移运算符

1.按位右移运算符(>>)

将数据除以2^n(2的n次方)

2.按位左移运算符(<<)

将数据乘以2^n(2的n次方)

使用按位运算符计算数据

#include<iostream>

using namespace std;

int main()

{

    cout << "Enter a number:";

    int Input = 0;

    cin >> Input;

    int Half = Input >> 1;

    int Quarter = Input >> 2;

    int Double = Input << 1;

    int Quadruple = Input << 2;

    cout << "Half:" << Half << endl;

    cout << "Quarter:" << Quarter << endl;

    cout << "Double:" << Double << endl;

    cout << "Quadruple:" << Quadruple << endl;

    return 0;

}
