1.按位右移運(yùn)算符(>>)
將數(shù)據(jù)除以2^n(2的n次方)

2.按位左移運(yùn)算符(<<)
將數(shù)據(jù)乘以2^n(2的n次方)

使用按位運(yùn)算符計(jì)算數(shù)據(jù)

#include <iostream>
#include <cstdlib>
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;

    system("pause");
    return 0;

}
