CPP – Nesting of member functions

Nesting of member functions

A member function called into another member function is referred to as nesting of member functions.

Example Program:

#include <iostream>
using namespace std;
class average
{
int a,b;
public:
void read();
void print();
int avg();
};
void average::read()
{
cout<<"\n enter a and b: ";
cin>>a>>b;
}
void average::print()
{
cout<<"value of a: "<<a;
cout<<"\nvalue of b: "<<b;
cout<<"\naverage is : "<<avg();
}
int average::avg()
{
return (a+b)/2;
}
main()
{
average A;
A.read();
A.print();
}

Output:
