Problem Statement

Create a `Box` class with a method `Box* getAddress()` that simply returns `this`. In `main()`, instantiate a `Box` named `b`, call `getAddress()`, and compare the returned pointer to the memory address of the object (`&b`). Print ‘Match’ if they are equal, otherwise ‘Mismatch’.

Input Format

None

Output Format

Print the exact message.

Constraints

None

Sample Output

Match

Explanation

The `this` pointer is an implicit hidden pointer passed to all non-static member functions, holding the memory address of the calling object.

Starter Code

#include <iostream>

class Box {
public:
    // Implement getAddress() returning this
};

int main() {
    // Instantiate Box, compare pointers, and print result
    return 0;
}
