Problem statement In this question first we will practice function overloading and then function templates. Please follow below instructions. 1. We can extend multiplication easily for string types if we interpret the operation as repetition. For example "code" * 3 may be interpreted as "codecodecode". In fact, languages like Python already support this operation. Write a C++ function named multiply that can multiply(repeat) an std::string by a given integer number and return the repeated string. 2. Write another C++ function named multiply that can multiply two given integer (int type) numbers and return the product as an integer. 3. Write another C++ function with the same name that can multiply a floating point number (double type) by a given integer number and return the product as a floating point number. 4. We defined three functions with the same name without a problem. It is either because they have a different number of parameters, or because any of their parameters are of a different type. This allows the compiler to recognize which one to consider, each function is unique though the names are same. 5. What if we can write a single function that can handle all three data types and give the results accordingly? We can do so using C++ function templates. Write a C++ function template named multiply_type that can take any floating point number(double type) or integer(int type) or an std::string as the first parameter and any integer number as the second and returns the respective product of the two. Do the following 1. Write your algorithm as code comments. I recommend to follow UMPIRE technique ( 2. Implement your functions (60) 3.

### Problem Statement

In this question, we will first practice function overloading and then function templates. Please follow the instructions below.

1. **String Multiplication**:
   - We can extend multiplication easily for string types if we interpret the operation as repetition. For example, the expression "code" * 3 may be interpreted as "codecodecode". In fact, languages like Python already support this operation.
   - **Task**: Write a C++ function named `multiply` that can multiply (repeat) an `std::string` by a given integer number and return the repeated string.

2. **Integer Multiplication**:
   - Write another C++ function named `multiply` that can multiply two integer (int type) numbers and return the product as an integer.

3. **Floating-Point Multiplication**:
   - Write another C++ function with the same name that can multiply a floating-point number (double type) by a given integer number and return the product as a floating-point number.

4. **Function Uniqueness**:
   - We defined three functions with the same name without a problem. It is either because they have a different number of parameters, or because any of their parameters are of a different type. This allows the compiler to recognize which one to consider; each function is unique though the names are the same.

5. **Function Templates**:
   - What if we want to write a single function that can handle all three data types and give the results accordingly? We can do so using C++ function templates.
   - **Task**: Write a C++ function template named `multiply_type` that can take any floating point number (double type) or integer (int type) or an `std::string` as the first parameter and any integer number as the second and return the respective product of the two.

### Do the Following

1. **Algorithm Comments**:
   - Write your algorithm as code comments. It is recommended to follow the UMPIRE technique.
   
2. **Function Implementation**:
   - Implement your functions.
   
3. **Testing**:
   - In your driver program, test your function for the criteria given below.
   - **Note**: This may be either fully or partially set up already in CodeCheck (20 points).

## Introduction to Multiplication Functions in C++

In this lesson, we will explore the implementation and testing of a function that multiplies values of different types in C++. We will cover function declarations, definitions, and the use of templates for generic programming.

### Function Implementation (`multiply.cpp`)

This section contains the implementation of various multiplication functions:

```cpp
// IMPLEMENT
#include "multiply.h"
std::string multiply(std::string string1, int number) {
    T return_value = T();
    for (int i = 0; i < number; ++i) {
        return_value += string1;
    }
    return return_value;
}

int multiply(int number1, int number2) {
    return number1 * number2;
}

double multiply(double number1, int number2) {
    return number1 * number2;
}
```

### Header File (`multiply.h`)

This header file declares the multiplication functions and provides a template for a more flexible multiply function:

```cpp
// IMPLEMENT
#ifndef MULTIPLY_H
#define MULTIPLY_H
#include <string>

std::string multiply(std::string string1, int number);
int multiply(int number1, int number2);
double multiply(double number1, int number2);

// In templates, we can't separate the declaration from the definition; We have to write it all together
template<class T>
T multiply_type(T entity, int number) {
    // Write your code below
    // You may need to initialize your return value like
    // T return_value = T();

    T return_value = T();
    for (int i = 0; i < number; ++i) {
        return_value += entity;
    }
    return return_value;
}

#endif // MULTIPLY_H
```

### Driver File (`multiply_driver.cpp`)

The driver file tests the multiplication functions:

```cpp
// REVIEW
#include <iostream>
#include "multiply.h"

// Replace ... with your code. Hit enter key to get more vertical space
int main(int argc, char *argv[]) {
    // Testing multiply
    std::cout << multiply(10, 10) << std::endl;
    // By exactly following the pattern above, test your function below for the rest of the tests in the order they are given

    std::cout << multiply(4, 6) << std::endl;
    std::cout << multiply(2.8, 10) <<
