Question

Need Help with this c++ problem

Write a pair of functions product which return the product of their arguments. The first takes two, and the second takes three.

### Examine the tester program to see how the functions are used.

---

#### File: `overload.cpp`

```cpp
#include "overload.h"

// Write your functions here
```

---

#### File: `overload.h`

```cpp
#ifndef OVERLOAD_H
#define OVERLOAD_H

#include <string>

#endif
```

---

#### File: `Tester.cpp`

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

#include "overload.h"

int main()
{
// 2 arguments
cout << "product(1.9, 3.4): " << product(1.9, 3.4) << endl;
cout << "Expected: 6.46" << endl;

// 3 arguments
cout << "product(7.5, 9.2, 2.1): " << product(7.5, 9.2, 2.1) << endl;
cout << "Expected: 144.9" << endl;
}
```

### Explanation

This code setup is used to demonstrate function overloading in C++.

- **`overload.cpp` and `overload.h`**: These files would typically contain function definitions and declarations. However, in this example, they are placeholders for you to write your functions.

- **`Tester.cpp`**: The main program file that includes the necessary headers and uses the `product` function, which is expected to be overloaded to handle different numbers of arguments. The program tests `product(1.9, 3.4)` expecting a result of 6.46, and `product(7.5, 9.2, 2.1)` expecting a result of 144.9.

By examining the output statements in `Tester.cpp`, users can see how function overloading allows the same function name to handle different numbers of parameters.

Expert Solution

Step 1

In this question we need to write a C++ program to overload product method such that one product method takes 2 parameters and other product method takes three parameter while each product method returns the product of passed arguments.
