2 (a) What is a copy constructor? Illustrate with a suitable C++ example. (2)

(b) Write the output of the following C++ code. Also, write the name of feature (2)
of Object Oriented Programming used in the following program jointly
illustrated by the Function 1 to Function 4.
void My_fun ( ) // Function 1
{
for (int I=1 ; I<=50 ; I++) cout<< "-" ;
cout<<end1 ;
}
void My_fun (int N) // Function 2
{
for (int I=1 ; I<=N ; I++) cout<<"*" ;
cout<<end1 ;
}
void My_fun (int A, int B) // Function 3
{
for (int I=1. ;I<=B ;I++) cout <<A*I ;
cout<<end1 ;
}
void My_fun (char T, int N) // Function 4
{
for (int I=1 ; I<=N ; I++) cout<<T ;
cout<<end1;
}
void main ( )
{
int X=7, Y=4, Z=3;
char C='#' ;
My_fun (C,Y) ;
My_fun (X,Z) ;
}

with respect to object oriented programming.
