Exercise A:

The objective of this exercise is to help you in understanding how C$++$ objects are shown on a memory

diagram, and how a member function of a class uses the $$this$$ pointer to access an object associated with a

particular function call.

What to Do:

$2$

Download files cplx$.$cpp$,$ cplx$.$h$,$ and lab$4$ExA.cpp from the D$2$L and draw AR diagrams for: point

one and point two.

For this exercise you just need to draw the diagrams. However, if you want to compile and run it from

command line, you should have all of the given files in the same directory and from that directory you should

use the following command to compile and create an executable:

g$++-$Wall cplx$.$cpp lab$4$ExA.cpp

Please notice that you shouldn$$t have the header file name$($s$)$ in this command.

What to Submit:

Submit your diagram as part of your lab report.

cplx$.$h:

#ifndef cplx$\_$h

#define cplx$\_$h

class Cplx $\{$

public:

Cplx$()$: realM$(-99),$ imagM$(-99)\{\}$

Cplx $($double r$,$ double i$)$;

double getRealPart $()$ const;

double getImaginaryPart $()$ const;

void setRealPart$($double arg$)$;

void setImaginaryPart$($double arg$)$;

Cplx add$($const Cplx& other$)$const;

Cplx subtract$($const Cplx$*$ other$)$const;

private:

double realM;

double imagM;

$\}$;

#endif $/*$ cplx$\_$h $*/$

cplx$.$cpp:

#include $"$cplx$.$h$"$

Cplx::Cplx$($double real $,$ double imag $)$: realM$($real$),$ imagM$($imag$)\{$

$//$ point one

$\}$

double Cplx::getRealPart$()$ const $\{$

return realM;

$\}$

double Cplx::getImaginaryPart$()$ const $\{$

return imagM;

$\}$

void Cplx::setRealPart$($double arg$)\{$

realM $=$ arg;

$\}$

void Cplx::setImaginaryPart$($double arg$)\{$

imagM $=$ arg;

$//$ point two

$\}$

Lab$4$ExA.cpp:

#include $"$cplx$.$h$"$

void global$\_$print$($const Cplx& n$)$;

int main$($void$)$

$\{$

Cplx num$1$;

num$1.$setRealPart$(666)$;

Cplx num$2(34,5)$;

num$1.$setImaginaryPart$(500)$;

return $0$;

$\}$

I included the AR diagram I made, please tell me if it's corect or not.Point $1$:
