C++ 代码：实现输入矩形长宽并计算其面积与周长

#include <iostream> using namespace std; int main() { float length, width, area, perimeter; cout << "请输入矩形的长度："; cin >> length; cout << "请输入矩形的宽度："; cin >> width; area = length * width; perimeter = 2 * (length + width); cout << "矩形的面积为：" << area << endl; cout << "矩形的周长为：" << perimeter << endl; return 0; } ######[AI写代码神器 | 260点数解答 | 2024-11-01 06:32:19]
