Problem statement In this question first we will practice function overloading and then function templates. Please follow below instructions. 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 PythonLinks to an external site. 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. Write another C++ function named multiply that can multiply two given integer (int type) numbers and return the product as an integer. 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. 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. 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.

![### C++ Code Implementation Tutorial
#### Code Implementation in `multiply.cpp`
Below are the definitions of three different `multiply` functions using C++ template programming. They are defined for strings, integers, and doubles.
```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){
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`
The `multiply.h` file contains declarations for the previously defined functions, along with a template function for generic types.
```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 in a single location.
template<class T>
T multiply_type(T entity1, 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 += entity1;
}
return return_value;
}
#endif // MULTIPLY_H
```
#### Driver File `multiply_driver.cpp`
Below is a driver program for testing the `multiply` functions defined earlier.
```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
}
