### Flowchart for the Below C++ Program

**Question:** Draw a flowchart to represent the below C++ program.

```cpp
1.  #include <iostream>
2.  using namespace std;
3.  int main()
4.  {
5.      int i = 1, n, in;
6.      cout << "ENTER A NUMBER ";
7.      cin >> n;
8.      while (i <= n)
9.      {
10.         cout << "\n";
11.         in = 1;
12.         while (in <= i)
13.         {
14.             cout << in;
15.             in = in + 1;
16.         }
17.         i = i + 1;
18.     }
19.     return 0;
20. }
```

### Explanation:

This C++ program outputs a pattern based on the user’s input. The flowchart will represent the following steps:

1. **Start**
2. **Include Headers**: Include iostream.
3. **Namespace Declaration**: Using namespace std.
4. **Main Function Start**: `int main()`.
5. **Initialize Variables**: `int i = 1, n, in;`.
6. **Output Message**: Prompt the user to enter a number.
7. **User Input**: Store user input in `n`.
8. **First `while` Loop Condition Check**: Check if `i` is less than or equal to `n`.
9. **New Line Output**: Output a new line.
10. **Initialize `in`**: Set `in` to 1.
11. **Second `while` Loop Condition Check**: Check if `in` is less than or equal to `i`.
12. **Output `in`**: Output the value of `in`.
13. **Increment `in`**: Increase `in` by 1.
14. **Repeat Inner Loop**: Go back to step 11.
15. **Increment `i`**: Increase `i` by 1.
16. **Repeat Outer Loop**: Go back to step 8.
17. **End Main Function**: Return 0.
18. **End**

### Diagram:

Below is the flowchart representation:

1. **Start**
2. **Include Headers**: iostream
3. **Namespace Declaration**: std
