Problem Statement

Create a `Logger` class with a `log(string)` method printing ‘Log: [msg]’. Create a `Serializable` class with a `serialize()` method printing ‘Serialized’. Create a `User` class inheriting both. Read a username, instantiate `User`, call `log(username)`, and call `serialize()`.

Input Format

A single string.

Output Format

Print the log message followed by 'Serialized'.

Constraints

None

Sample Input

Admin

Sample Output

Log: Admin
Serialized

Explanation

Multiple inheritance is heavily used in C++ to design "Mixins"—small classes that inject specific capabilities into larger objects.

Starter Code

#include <iostream>
#include <string>

class Logger {
public:
    // Implement log method
};

class Serializable {
public:
    // Implement serialize method
};

class User {
    // Inherit Logger and Serializable
};

int main() {
    // Read input, instantiate, and call methods
    return 0;
}
