Generic 3 - Answer All Question

When a copy constructor is called?

Write with example how will you dynamically initialize objects?

What are advantages of declaring constructors and destructor under public accessability?

Rewrite the following program after removing the syntax errors if any and underline the errors:
#include< iostream >
#include< stdio.h >
classmystud
{ intstudid =1001;
char name[20];
public
mystud( )
{ }
void register ( ) {cin >> stdid;gets(name);
}
void display ( )
{ cout << studid << ":" << name << endl; }
}
int main( )
{ mystud MS;
register.MS( );
MS.display( );
}

Given the following C++ code, answer the questions (i) & (ii).
class TestMeOut
{
public:
~TestMeOut() //Function 1
{cout<< “Leaving the examination hall”< TestMeOut() //Function 2
{cout<< “Appearing for examination”< void MyWork() //Function 3
{cout<< “Attempting Questions//< };
(i) In Object Oriented Programming, what is Function 1 referred as and when doesit get invoked / called ?
(ii) In Object Oriented Programming, what is Function 2 referred as and when doesit get invoked / called ?

Write the output of the following C++ program code :
#include
using namespace std;
class Calci
{
char Grade;
int Bonus;
public:
Calci() {Grade='E'; Bonus=0;} //ascii value of A=65
void Down(int G)
{
Grade-=G;
}
void Up(int G)
{
Grade+=G;
Bonus++;
}
void Show()
{
cout<< Grade << "#" << Bonus << endl; }
};
int main()
{
Calci c;
c.Down(3);
c.Show();
c.Up(7);
c.Show();
c.Down(2);
c.Show( );
return 0;
}

Differentiate implicit call and explicit call of involving parameterized constructor.
