How to Implement a Copy Constructor for Deep Copying?

// C++ Program that illustrates the Implementation of Copy
// Constructor for Deep Copying
#include <cstring>
#include <iostream>
using namespace std;

class Student {
public:
    int roll;
    char* name;
    Student(int roll)
        : roll(roll)
    {
        name = new char[100]; // Allocate memory for name
    }

    void setName(const char* name)
    {
        strcpy(this->name, name);
    }

    // Implementing a deep copy constructor
    Student(const Student& other)
        : roll(other.roll)
    {
        name = new char[strlen(other.name) + 1];
        strcpy(name, other.name);
    }

    // Implementing the copy assignment operator for deep
    // copying
    Student& operator=(const Student& other)
    {
        if (this != &other) { // Prevent self-assignment
            roll = other.roll;
            delete[] name; // Free existing name memory
            name = new char[strlen(other.name) + 1];
            strcpy(name, other.name);
        }
        return *this;
    }

    // Implementing a destructor to deallocate dynamically
    // allocated memory
    ~Student() { delete[] name; }
};

int main()
{
    // Create an object
    Student s1(100);
    s1.setName("John");
    cout << "Original Object: " << s1.name << endl;

    // Creating a copy of the object s1
    Student s2 = s1; // Use copy constructor
    cout << "Copy Object: " << s2.name << endl;

    // Making changes in the data member of the copy object
    s2.name[0] = 'S';

    // Printing data members of both objects after making
    // changes in copy object
    cout << "After Changes:" << endl;
    cout << "Original Object: " << s1.name << endl;
    cout << "Copy Object: " << s2.name << endl;

    return 0;
