Question
**Summary**

In this lab, the completed program should print the numbers 0 through 10, along with their values multiplied by 2 and by 10. You should accomplish this using a `for` loop instead of a counter-controlled `while` loop.

**Instructions**

1. Write a `for` loop that uses the loop control variable to take on the values 0 through 10.

2. In the body of the loop, multiply the value of the loop control variable by 2 and by 10.

3. Execute the program by clicking the Run button at the bottom of the screen. Is the output the same?

**C++ Code Explanation**

The provided code segment is in C++:

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

int main()
{
    string head1 = "Number: ";
    string head2 = "Multiplied by 2: ";
    string head3 = "Multiplied by 10: ";
    int numberCounter;           // Numbers 0 through 10
    int byTen;                   // Stores the number multiplied by 10
    int byTwo;                   // Stores the number multiplied by 2
    const int NUM_LOOPS = 10;    // Constant used to control loop

    // This is the work done in the housekeeping() function
    cout << "0 through 10 multiplied by 2 and by 10." << endl;

    // This is the work done in the detailLoop() function
    // Write your for loop here.

    // This is the work done in the endOfJob() function
    return 0;
} // End of main()
```

**Explanation:**

- **Headers Included:**
  - `<iostream>`: For input-output stream operations.
  - `<string>`: For using string data types.

- **Namespace:**
  - `using namespace std;`: To avoid prefixing standard library functions with `std::`.

- **Main Function:**
  - Declares three string variables for headings.
  - `int numberCounter;` is intended for iterating numbers from 0 to 10.
  - `int byTen;` and `int byTwo;` to store multiplication results.
  - `const int NUM_LOOPS = 10;` is a constant to control
