C程序返回矩形的周长和面积

#include <stdio.h>

struct Rectangle {
    float length;
    float width;
};

// 计算矩形的周长
float calculatePerimeter(struct Rectangle rectangle) {
    return 2 * (rectangle.length + rectangle.width);
}

// 计算矩形的面积
float calculateArea(struct Rectangle rectangle) {
    return rectangle.length * rectangle.width;
}

int main() {
    struct Rectangle rectangle;
    
    // 输入矩形的长和宽
    printf("请输入矩形的长和宽：\n");
    scanf("%f %f", &rectangle.length, &rectangle.width);
    
    // 计算并输出矩形的周长和面积
    printf("矩形的周长为：%f\n", calculatePerimeter(rectangle));
    printf("矩形的面积为：%f\n", calculateArea(rectangle));
    
    return 0;
}
