Instructions Redo Programming Exercise 1 by overloading the operators as nonmembers of the class rectangleType. The header and implementation file from Exercise 1 have been provided. Write a test program that tests various operations on the class rectangleType.

main.cpp:

#include

#include "rectangleType.h"

int main()

{

rectangleType r1(5, 10);

rectangleType r2(10, 20);

rectangleType r3 = r1 + r2;

std::cout << "r3 length: " << r3.getLength() << std::endl;

std::cout << "r3 width: " << r3.getWidth() << std::endl;

return 0;

}

rectangleType.cpp:

#include "rectangleType.h"

rectangleType operator+(const rectangleType& r1, const rectangleType& r2)

{

rectangleType result;

result.setLength(r1.getLength() + r2.getLength());

result.setWidth(r1.getWidth() + r2.getWidth());

return result;

}
