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

int privateData;

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");

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

return 1;

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