[C++知识库]【C++】对象数组作业4

#include <iostream>
#include "Rectangle.h"

using namespace std;


int main(){
    const int N = 3;

    Rectangle *pRectangle[N];
    int width,height;

    for (int i = 0; i < N; ++i) {
        cout << "请输入第" << i << "个矩形的宽度和高度";
        cin >> width >> height;
        pRectangle[i] = new Rectangle(width,height);
        pRectangle[i] -> display();
    }

    for (int i = 0; i < N; ++i) {
        delete pRectangle[i];

    }
    return 0;
}

不太理解，明天再看看。

输出结果
