Question
Need some help writing functions for this problem.
Write a pair of functions cube which return the cube of their arguments.
Transcribed Image Text:## C++ Code Implementation
This example illustrates the basic use of C++ header and source files to calculate the cube of different numbers. The project consists of three files: `cube.cpp`, `cube.h`, and `Tester.cpp`.
### cube.cpp
```cpp
#include "cube.h"
// Write your functions here
```
This is the source file where functions are to be implemented. Currently, it includes `cube.h`, but the function definitions are to be added by the user.
### cube.h
```cpp
#ifndef CUBE_H
#define CUBE_H
#endif
```
This is the header file using include guards (`#ifndef`, `#define`, `#endif`) to prevent multiple inclusions. It's set up to be expanded with function declarations.
### Tester.cpp
```cpp
#include <iostream>
#include <iomanip>
using namespace std;
#include "cube.h"
int main()
{
cout << "cube(2.5): " << cube(2.5) << endl;
cout << "Expected: 15.625" << endl;
cout << "cube(7): " << cube(7) << endl;
cout << "Expected: 343" << endl;
cout << "cube(9.8): " << cube(9.8) << endl;
cout << "Expected: 941.1920000000002" << endl;
cout << "cube(5.9): " << cube(5.9) << endl;
cout << "Expected: 205.37900000000002" << endl;
cout << "cube(9): " << cube(9) << endl;
cout << "Expected: 729" << endl;
cout << "cube(2): " << cube(2) << endl;
cout << "Expected: 8" << endl;
}
```
This file performs several tests to calculate the cube of various numbers using a function expected to be defined in `cube.cpp`. It includes:
- `#include <iostream>` and `#include <iomanip>` for basic input/output and formatting.
- Multiple `cout` statements to display calculated cube values along with their expected results.
### Explanation
- **Headers and Guards**: The header guard in `cube.h` helps in preventing the file from being included multiple times, which can lead to errors.
- **Main Function**: The `main` function in `Tester
Expert Solution
Step 1
A pair of functions cube which returns the cube of their arguments.
Solution :
#include <"cube.h">
//cube() function
int cube(int num) {
int c;
c=num*num*num;
return c;
}
//cube() function
double cube(double num) {
double c;
c=num*num*num;
return c;
}
