c++ operator

// C++ Operator Example

#include <iostream>
using namespace std;

int main() {
    // Arithmetic Operators
    int a = 10;
    int b = 5;
    cout << "a + b = " << a + b << endl; // Addition operator
    cout << "a - b = " << a - b << endl; // Subtraction operator
    cout << "a * b = " << a * b << endl; // Multiplication operator
    cout << "a / b = " << a / b << endl; // Division operator
    cout << "a % b = " << a % b << endl; // Modulus operator

    // Comparison Operators
    cout << (a == b) << endl; // Equality operator
    cout << (a != b) << endl; // Not equal to operator
    cout << (a > b) << endl;  // Greater than operator
    cout << (a < b) << endl;  // Less than operator
    cout << (a >= b) << endl; // Greater than or equal to operator
    cout << (a <= b) << endl; // Less than or equal to operator

    // Logical Operators
    bool x = true;
    bool y = false;
    cout << (x && y) << endl; // Logical AND operator
    cout << (x || y) << endl; // Logical OR operator
    cout << (!x) << endl;     // Logical NOT operator

    // Bitwise Operators
    int c = 6; // binary: 110
    int d = 2; // binary: 010
    cout << (c & d) << endl; // Bitwise AND operator
    cout << (c | d) << endl; // Bitwise OR operator
    cout << (c ^ d) << endl; // Bitwise XOR operator
    cout << (c << 1) << endl; // Left shift operator
    cout << (c >> 1) << endl; // Right shift operator

    // Assignment Operators
    int e = 10;
    e += 5; // Equivalent to e = e + 5
    cout << "e = " << e << endl;

    return 0;
}

解释说明：

• 算术运算符：用于执行基本的数学运算，如加法、减法、乘法、除法和取模。
• 比较运算符：用于比较两个值，返回一个布尔结果（true 或 false）。
• 逻辑运算符：用于组合或反转布尔表达式的结果。
• 位运算符：用于对整数进行按位操作，如按位与、或、异或、左移和右移。
• 赋值运算符：用于将一个值赋给一个变量，还可以与其他运算符结合使用（如 +=）。
