#include <iostream> using namespace std; int main() { int x, y; cin >> x >> y; // 计算 x@y int result1 = x * x + y * y - x * y; cout << result1 << endl; // 计算 x@(x+y) int sum = x + y; int result2 = x * x + sum * sum - x * sum; cout << result2 << endl; return 0; } c++
这段代码实现了自定义运算 `x@y = x² + y² - xy` 的计算。 代码功能： 1. 输入两个整数 `x` 和 `y`。 2. 计算 `x@y` 并输出结果。 3. 计算 `x@(x+y)` 并输出结果。 运算示例： 输入： ``` 3 4 ``` 计算过程： 1. `3@4 = 3² + 4² - 3×4 = 9 + 16 - 12 = 13` 2. `3@(3+4) = 3² + 7² - 3×7 = 9 + 49 - 21 = 37` 输出： ``` 13 37 ``` 代码说明： - 使用 `cin` 读取两个整数。 - 直接套用公式计算两个结果。 - 使用 `cout` 输出结果，每个结果占一行。 这段代码简洁明了地完成了指定运算的计算任务。 [2025-12-13 15:08:14 | AI问答 | 215点数解答]
