Inheritance is deriving a new class or classes from its base
class or classes.
Inheritance is of basically five types:
-Single inheritance
-Multiple inheritance
-Multilevel inheritance
-Hierarchical inheritance
-Hybrid inheritance

There are three modes by which we can inherit a class.
1.Private visibility mode
2.Public visibility mode
3.Protected visibility mode

Eg:-

#include<iostream>
using namespace std;
class base
{
private:
int a;
public:
void geta()
{
cout<<"\nEnter the value of 'a':;
cin>>a;
}
void puta()
{
cout<<"\nValue of 'a' is:"<<a;
}
};
class derived:public base //base class is ...
{ //publically inherited
private:
int b;
public:
void getb()
{
cout<<"\nEnter the value of b:";
cin>>b;
}
void putb()
{
cout<<"\nValue of b is:"<<b;
}
};
int main()
{
derived d;
d.geta();
d.puta();
d.getb();
d.putb();
return 0;
}
