c++ - Rectangle class -

hi im new c++ , may in on head on problem im trying solve. visual explanation , solution errors or better revised source code ask of. invest there interest question.

heres problem: design class named rectangle represent rectangle. class must contain:

• two double data fields named width , height specify width , height of rectangle.
• a no-arg constructor creates default rectangle width 1 , height 1.
• a constructor creates rectangle specified width , height
• the accessor , mutator functions data fields
• the function named area() returns area of rectangle
• a function named getperimeter() returns peremter.

draw uml diagram class. implement class. write test progranm creates 2 rectangle obejects. assign width 4 , height 40 first object , width 3.5 , height 35.9 second. display properties of both objects , find areas , perimeters.

heres have far:

#include <iostream> using namespace std;  class rectangle {     public:         double height;  public:   double width;   rectangle()   {       width = 4;           }    rectangle(double newarea)    double height;   height()   (       height = 40       {           {           area = height* width;           }     double getarea()   {     return area;   }    bool ison()   {     return on;   }     double getperimeter()   {     return perimeter;   }    void setperimeter(double radius)    cout << "the area of  rectangle"   << rectangle1.area<<"is"<<rectangle1.getarea()<< endl;  cout<<"the area of  rectangle"  <<rectangle.area2.area<<"is"<<rectangle2.getarea()<<endl;      return 0; } 

if you'd learn whats going on here, check out

#include <iostream>  using namespace std;   class rectangle{  private:        // in cases want keep member variables private   double height;    // allows of how accessed.    double width;     // provides level of security class.  public:         // need 1 public:   // constructors called when define new variable of type rectangle   rectangle()       // no arguments means constructor takes no input when called.   {      width = 1.0;        // sets width , height 1     height = 1.0;   }    rectangle(double a_width, double a_height) {  // constructor needs exact(case-sensitive) match of class-name     /* set width , hieght arguments passed constructor in here.*/            }    // accessor / mutator methods more called get/set methods.   double getheight(){   // height called on rectangle class     return height;      // returns value of class member "height"   }    /*make method width here.*/    // in c++ can return results of equations directly   // i.e.    // int x = 2;   // return x*x;  // returns 4   // try simliar getarea() , getperimeter();    double getarea() const    {        return /*area equation goes here*/ ;   }    double getperimeter() const   {                          return /*perimeter equation goes here*/;    }  }   // should split these displaying statements main function,   // meant do, right? ;)   int main(){     // in order use new class, need declare variable of type       rectangle rectangle1;            // when declare new variable without arguments default constructor called.       // means rectangle class decides use height = 1; width = 1; constructor above.       // can check using getheight() , getwidth(), when implement them.        cout << "the area of rectangle is" << rectangle1.getarea() << endl;     return 0;  }
