#include <iostream>
using namespace std;
int main()
{
    //逻辑运算符 与 && 同真为真，其余为假
    int a = 10;
    int b = 10;
    cout << (a&&b)<< endl;//都真


    a = 0;
    b = 10;
    cout << (a && b) << endl;//一个结果为假，结果假



    a = 0;
    b = 0;
    cout << (a && b) << endl;//一个结果为假，结果假


    system("pause");
    return 0;
