下面是补全后的代码：

#include <iostream>
#include <cmath>

using namespace std;

//定义Point类
class Point {
public:
    int x, y;
    Point(int x, int y) : x(x), y(y) {}
};

//定义Rect类
class Rect {
public:
    Point tl, br;
    Rect(Point tl, Point br) : tl(tl), br(br) {}

    // 返回矩形的左下角坐标
    Point bottomLeft() const {
        return Point(tl.x, br.y);
    }

    // 返回矩形的右上角坐标
    Point topRight() const {
        return Point(br.x, tl.y);
    }

    // 返回矩形的宽度
    int width() const {
        return abs(br.x - tl.x);
    }

    // 返回矩形的高度
    int height() const {
        return abs(br.y - tl.y);
    }

    // 返回矩形的面积
    int area() const {
        return width() * height();
    }

    // 返回矩形对角线的长度
    double diagonalLength() const {
        return sqrt(pow(width(), 2) + pow(height(), 2));
    }
};

int main() {
    auto rt = Rect(Point(1,6), Point(7,8));

    printf("Vertices of rectangle rt:\n");
    printf("(%d,%d)-----------------------(%d,%d)\n", rt.tl.x, rt.tl.y, rt.topRight().x, rt.topRight().y);
    printf("(%d,%d)-----------------------(%d,%d)\n", rt.bottomLeft().x, rt.bottomLeft().y, rt.br.x, rt.br.y);

    printf("Size information of rectangle rt:\n");
    printf("width - %d        height - %d\n", rt.width(), rt.height());
    printf("area - %d        diagonal legnth - %.2f", rt.area(), rt.diagonalLength());

    return 0;
