[数据结构与算法]敲代码的第一天：创建函数并调用求长方形面积（c++）

1.Rectangle.h

#include<iostream>
using namespace std;
class Rectangle {
private:
    int height;
    int width;
public:
    Rectangle();
    Rectangle(int height, int width);
    int getPerimeter();
    int getPArea();
    void print();
};

2.Rectangle.cpp

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

using namespace std;
Rectangle::Rectangle() {
? ? cout << "无参构造函数被调用了"<< endl;
}
Rectangle::Rectangle(int height,int width){
this->height = height;
this->width = width;
}
int Rectangle::getPerimeter(){
? ? return (width+height)*2;
}
int Rectangle::getPArea(){
? ? return width*height;
}
void Rectangle::print(){
? ? cout<<"长度是："<<width<<",高度是："<<height<<endl;
}

3.TestRectangle.cpp

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

using namespace std;
int main() {
? ? int height,width;
? ? cout <<"请输入长度"<<endl;
? ? cin>>width;
? ? cout <<"请输入高度"<<endl;
? ? cin>>height;
? ? Rectangle rectangle(height,width);
? ? rectangle.print();
? ? int r = rectangle.getPArea();
? ? int p = rectangle.getPerimeter();
? ? cout<<"面积是："<<r<<endl;
? ? cout<<"周长是："<<p<<endl;
? ? return 0;
}
