赋值运算符：

 代码演示：

#include
using namespace std;

int main()
{
    //赋值运算符
    
    // =
    int a = 10;
    a = 100;//重新赋值
    cout << "a = " << a << endl;
    
    // +=
    int b = 10;
    b += 2;//本质是 b = b + 2
    cout << b << endl;
    
    
    int c = 10;
    c -= 2;
    cout << c << endl; //8
    
    int d = 10;
    d *= 2;
    cout << d << endl; //20
    
    int e = 10;
    e /= 2;
    cout << e << endl; //5
    
    // 模等于 %= 与上基本同样
    int f = 10;
    f %= 2;//本质是 a = a % 2
    cout << f << endl;
    //输出结果为：0
    
    system("pause");
    return 0;
}
