5.3 MEMBER FUNCTIONS

Just like data members class also has member functions. We need member functions to access private data members. Let us add two member functions³ (or methods) to the class Date which was declared earlier.

Problem: Write a program to demonstrate the use of public method in accessing private data members.

Solution: See Program 5.2.

Program 5.2 Introducing methods

// date1.cpp#include<iostream.h>//Class declaration begins hereclass Date{ private :    int day, month, year; // data members  public :    void setDate(int d1,int m1,int y1);// member function or method    void showDate(); //member function or method};//Class declaration ends here.//Method definitions are given after function mainint main(){ Date d1;  cout<< “<---date1.cpp--->”<<endl; ...
