C++ 交换两个整数的值 - 代码示例

#include\nusing namespace std;\n\nvoid swap(int& a, int& b) {\n int temp = a;\n a = b;\n b = temp;\n}\n\nint main() {\n int num1, num2;\n cout << "请输入两个整数：" << endl;\n cin >> num1 >> num2;\n \n cout << "交换前的值：" << endl;\n cout << "num1 = " << num1 << endl;\n cout << "num2 = " << num2 << endl;\n \n swap(num1, num2);\n \n cout << "交换后的值：" << endl;\n cout << "num1 = " << num1 << endl;\n cout << "num2 = " << num2 << endl;\n \n return 0;\n}
