Write a c++ Program to get the average marks of six subjects using the Multiple Inheritance With output

Sure! Below is a simple C++ program that demonstrates multiple inheritance to calculate the average marks of six subjects. In this example, we'll have two base classes: `SubjectMarks` to store the marks for each subject, and `AverageMarks` to compute the average using the marks from `SubjectMarks`. The derived class `Student` will inherit from both base classes.

Here's the implementation:

```cpp
#include <iostream>
using namespace std;

// Base class to hold marks for six subjects
class SubjectMarks {
protected:
    float marks[6];

public:
    void inputMarks() {
        cout << "Enter marks for six subjects:\n";
        for (int i = 0; i < 6; i++) {
            cout << "Subject " << (i + 1) << ": ";
            cin >> marks[i];
        }
    }
};

// Base class to calculate average marks
class AverageMarks {
protected:
    float average;

public:
    void calculateAverage(float marks[]) {
        float sum = 0;
        for (int i = 0; i < 6; i++) {
            sum += marks[i];
        }
        average = sum / 6;
    }

    void displayAverage() {
        cout << "Average Marks: " << average << endl;
    }
};

// Derived class that inherits from SubjectMarks and AverageMarks
class Student : public SubjectMarks, public AverageMarks {
public:
    void compute() {
        inputMarks();              // Get marks from user
        calculateAverage(marks);   // Calculate average
        displayAverage();          // Display average
    }
};

int main() {
    Student student;  // Create an instance of Student
    student.compute(); // Call compute to process marks and output average
    return 0;
}
```

### How the Program Works:

1. **SubjectMarks Class**: This class contains an array to store the marks of six subjects and a function to input these marks.
   
2. **AverageMarks Class**: This class contains a function to compute the average of the marks provided from the `SubjectMarks` class's array and a function to display the average.

3. **Student Class**: This class inherits from both `SubjectMarks` and `AverageMarks`. It has a method `compute()` that orchestrates the calling of input and processing functions.

4. **Main Function**: The main function creates an instance of the `Student` class and calls the `compute()` method, which handles the entire process.

### Example Output
Below is an example of what the output would look like when a user runs the program and provides input:

```
Enter marks for six subjects:
Subject 1: 85
Subject 2: 90
Subject 3: 78
Subject 4: 88
Subject 5: 92
Subject 6: 95
Average Marks: 88.6667
```

### Note:
- Ensure the input values for the marks are valid numbers (0-100 for marks).
- C++ compilers need to be set up for your execution environment and you should compile it properly to see the results.
