How to Access Private Data Members in C++ Without Using Friend Function

You can refer the below YouTube Video in which I have explained the complete program. Example code is given below.

#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
#include <string.h>

class Test
{
private:
int privateData;

public:
Test(int data1)
{
privateData = data1;
}
void display();
};

void Test::display()
{
printf("Value of private data = %d\n", privateData);
}

int main()
{
Test obj1(97);
printf("Before Change:\n");
obj1.display();

int *p = (int *) &obj1;
*p = 43;
printf("Violate the Object Oriented Programming Concept\n");
printf("After Change:\n");
obj1.display();

getch();
return 1;
}

Note:-
Accessing the private data using this type of algorithm is against Object Oriented Concept.
