$1-$Implement a header and implementation file for class Rectangle. Rectangle

should include a single integer data member length, a constructor, an accessor,

a mutator and a member print function. Be sure to include preprocessor

directives and include statements as needed.

driver.cpp

#include

#include "Square.h$"$

int main $()\{$

$//$Y$.$Cercioglu

std:: cout $<<"$

$"$;

$//$ Instantiate an object of type Square with a side length of $5$

Square mySquare;

mySquare.setSide$(5)$;

$//$ Print the initial state of the square

std::cout $<<$ "Initial state of the square:" $<<$ std::endl;

print$($mySquare$)$;

$//$ Using accessor function to get the side length of the square

std::cout $<<$ "The side length of the square is: $"<<$ mySquare.getSide$()<<$ std::endl;

$//$ Using the mutator function to change the side length of the square to $10$

mySquare.setSide$(10)$;

std::cout $<<$ "The side length of the square is: $"<<$ mySquare.getSide$()<<$ std::endl;

$//$ Printing the state of the square after modifying its side length

std::cout $<<$ "State of the square after changing its side length:" $<<$ std::endl;

print$($mySquare$)$;

return $0$;

$\}$

$2-$Update driver.cpp to instantiate an object of type Rectangle and test all

Rectangle functions.
