Explain the different types of inheritance.

Explain the different visibility mode through pictorial representation.

Consider the following c++ code and answer the questions
class Personal
{
int Class,Rno;
char Section;
protected:
char Name[20];
public:
personal();
void pentry();
voidPdisplay();
};
class Marks:private Personal
{
float M{5};
protected:
char Grade[5];
public:
Marks();
void M entry();
void M display();
};
class Result:public Marks
{
float Total,Agg;
public:
char FinalGrade, Commence[20];
Result();
void R calculate();
void R display();
}:
(i) Which type of Inheritance is shown in the program?

#include< iostream >
#include< string >
#include
using name spacestd;
class publisher
{
char pname[15];
char hoffice[15];
char address[25];
double turnover;
protected:
char phone[3][10];
void register( );
public:
publisher( );
~publisher( );
void enter data( );
void disp data( );
};
class branch
{
charbcity[15];
char baddress[25];
protected:
intno_of_emp;
public:
charbphone[2][10];
branch( );
~branch( );
void have data( );
void give data( );
};
class author: public branch, publisher
{
intaut_code;
charaname[20];
float income;
public:
author( );
~author( );
voidgetdata( );
voidputdata( );
};

Write the output of the following program
#include< iostream >
using namespace std;
class A
{
protected:
int x;
public:
void show()
{
cout<<"x = "<<x<<endl;}
A()
{
cout<<endl<<" I am class A "<<endl;}
~A( )
{
cout<<endl<<" Bye ";} };
};
class B : public A
{
protected:
int y;
public:
B(int x, int y)
{ x = x1;
y = y1; }
B( )
{
cout<<endl<<" I am class B "<<endl; }
~B( )
{
cout<<endl<<" Bye "; }
void show( )
{
cout<<"x = "<<x<<endl;
cout<<"y = "<<y<<endl; }
};
int main( )
{
A objA;
B objB(30, 20);
objB.show( );
return 0;
}
