Nested member function in c++

 NESTING OF MEMBER FUNCTION;

A member function can be called by using its name inside another member function of the

same class. This is known as nesting of member functions.

#include <iostream.h>

class set

{

int m,n;

public:

void input(void);

void display (void);

void largest(void);

};

int set::largest (void)

{

if(m>n)

return m;

else

return n;

}

void set::input(void)

{

cout<<”input values of m and n:”;

cin>>m>>n;

}

void set::display(void)

{

cout<<”largestvalue=”<<largest()<<”\n”;

}

void main()

{

set A;

A.input( );

A.display( );

}

output:

Input values of m and n:

3017

largest value= 30
