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 (6 3. In your driver program, test your function for the criteria given below. Note that this may be either fully or partially set up already in CodeCheck. points)

In this question, we will first practice function overloading and then function templates. Please follow the instructions below:
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 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 the 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 following UMPIRE techniques.
2. Implement your functions.
3. In your driver program, test your function for the criteria given below. Note that this may be either fully or partially set up already in CodeCheck.
## Criteria

Transcribed Image Text:### Understanding Multiply Function Templates in C++
This section provides a detailed explanation of the `multiply` function templates in C++.
#### 1. multiply.cpp
This file contains the function definitions for the `multiply` function.
```cpp
// Replace ... with your code. Hit enter key to get more vertical space
// IMPLEMENT
#include "multiply.h"
std::string multiply(std::string string1, int number){
...
}
int multiply(int number1, int number2){
...
}
double multiply(double number1, int number2){
...
}
```
- **`multiply(std::string string1, int number)`**:
This function definition is intended to multiply a string by an integer to repeat the string `number` of times.
- **`multiply(int number1, int number2)`**:
This function multiplies two integers.
- **`multiply(double number1, int number2)`**:
This function multiplies a double by an integer.
#### 2. multiply.h
This header file contains the declarations of the `multiply` functions and a template class for any type of multiplication.
```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 definition;
// We have to write it in a single location.
template<class T>
T multiply(T entity1, int number){
// Write your code below
// You may need to initialize your return value like,
// T return_value = T();
...
}
#endif // MULTIPLY_H
```
- **`multiply` Function Declarations**:
- **String and Integer**: This declares a function to repeat a string a specified number of times.
- **Two Integers**: This declares a function to multiply two integers.
- **Double and Integer**: This declares a function to multiply a double by an integer.
- **Template Class `multiply`**:
This allows any type `T` to be multiplied by an integer, ensuring generic functionality.
#### 3. multiply_driver.cpp
This file is used to test the `multiply` functions defined in `multiply.cpp`.
```cpp
// REVIEW
#include <iostream>
#include "multiply.h"
// Replace ...
