Data Hiding in C++

Introduction

In object-oriented programming, data hiding is an important concept that allows us to protect the internal data of a class from being accessed or modified directly by external code. This helps in maintaining the integrity and encapsulation of the class.

In this code example, we will explore the concept of data hiding in C++. We will create a class called "Base" that demonstrates how to hide data members and provide controlled access to them using member functions.

Key Concepts

• Data Hiding: Data hiding is the practice of encapsulating data within a class and providing controlled access to it through member functions. This prevents direct access to the data from external code, ensuring data integrity and encapsulation.
• Private Access Specifier: In C++, the private access specifier is used to declare members that are only accessible within the class. Private members cannot be accessed or modified directly by external code.
• Public Member Functions: Public member functions are used to provide controlled access to private data members. These functions can be called from external code to perform operations on the hidden data.

Code Structure

#include<iostream>
using namespace std;
class Base
{
	int num;
	public:
		void getData();
		void showData();
};
void Base::getData()
{
	cout<<"Enter Any Integer Vlaue:"<<endl;
	cin>>num;
}
void Base::showData()
{
	cout<<"The Value Is:"<<num<<endl;
}
int main()
{
	Base obj;
	obj.getData();
	obj.showData();
}
