help w/another program!!!
i have this object program and it basically works but when it returns length, area, etc it gives me a negative totally incorrect answer help??!!
for more info look at thread called Rectangle class
// rectangle.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <iostream>
using namespace std;
class Rectangle{
public:Rectangle();
Rectangle(float urx, float ury, float ulx, float uly, float llx,float lly, float lrx, float lry);
void calclength(float urx, float ulx);
void calcwidth(float ury, float lry);
float area();
float perimeter();
void setlength(float lrx, float llx);
void setwidth(float uly, float lly);
void print();
float getlength();
float getwidth();
bool square(float urx, float ury, float lrx, float lry);
private:float upprx, uppry, upplx, upply, lowrx, lowry,length, width, lowlx, lowly;
