Suppose that these two statements were sequentially appearing within your Rectangle program’s main() method. Is the statement r.length = 50; a valid statement? Explain your answer. Rectangle r; r.length = 50; also, In reference to the program statements of the completed starter code file, what is the classification of the setValues() member function? Is it an accessor function or a mutator function?
#include <iostream>
using namespace std;
class Rectangle { // define class
public:
Rectangle() { length = 0; width = 0; } // constructor
float getlength() { return length; } // return length
float getWidth() { return width; } // return width
float area() { return length* width; } // return area
float perimeter() { return 2 * length + 2 * width; }
void setValues(float, float);
private:
float length, width;
};
void Rectangle::setValues(float len, float wid)
{
if (len <= 0 || len >= 20) {
cout << "Enter new value for length ";
cin >> len;
}
length = len;
if (wid <= 0 || wid >= 20) {
cout << "Enter new value for width ";
cin >> wid;
}
width = wid;
}
int main() {
float length, width;
Rectangle r;
cout << "Enter a value for length and width between 0 and 20\n";
cin >> length >> width;
r.setValues(length, width);
cout << "\nGiven the length of " << r.getlength()
<< " and the width of "
<< r.getWidth() << " \nyour area is " << r.area()
<< " and your perimeter is "
<< r.perimeter() << "\n\n";
system("pause");
return 0;
}
(5) Suppose that these two statements were sequentially appearing within your Rectangle program’s main() method. Is the statement
r.length = 50; a valid statement? Explain your answer.
Rectangle r;
r.length = 50;
