PROGRAMMING LANGUAGE: C++

SUBJECT: OOP

 

Task: Find errors in the following code and rewrite a correct version of code with outputs.

#include <iostream>

using namespace std;

class CRectangle {

int width. height;

public:

void set_values (int, int);

int area () {return (width * height);}

};

void CRectangle::set_values (int a, int b) {

width = a;

height = b;

}

int main () {

CRectangle a,*b,*c;

c= a;

a.set_values (1,2);

b= new CRectangle;

c=&b;

c->set_values (3,4);

cout << "a area: " << c->area() << endl;//

cout << "*b area: " << a.area() << endl;//

c->set_values (5,6);

cout << "*b area: " << b.area() << endl;//

delete b;

return 0;
