rect.cpp

c++程序设计教材第二版书上即课后习题源代码

#include <iostream>
#include "rect.h"
using namespace std;

Rectangle::Rectangle(int l , int t, int r, int b) {
	left = l; top = t;
	right = r; bottom = b; 
} // 构造函数，带默认参数，缺省值为全0，在声明中指定
void Rectangle::Assign(int l, int t, int r, int b){
	left = l; top = t;
	right = r; bottom = b;
}
void Rectangle::Show(){
	cout<<"left-top point is ("<<left<<","<<top<<")"<<'\n';
	cout<<"right-bottom point is ("<<right<<","<<bottom<<")"<<'\n';
}
