### Understanding Nested If-Else Statements in C#

In this tutorial, we will discuss how to properly implement a nested if-else statement in C# to determine the game status based on the value of an integer variable `num`. Assume that `num` is an integer variable that has been declared and initialized. The possible values for `num` range between 2 and 12. 

Here's what we want our program to do:

- Output "Game status is WON" if `num` is 7 or 11.
- Output "Game status is LOST" if `num` is 2, 3, or 12.
- Output "Game status is CONTINUE" if `num` is 4, 5, 6, 8, 9, or 10.

To achieve this, we will use nested if-else statements. Nested if-else statements allow us to check multiple conditions based on the preceding conditions. Below is a detailed breakdown of how to write this logic in C#:

### Code Explanation

```csharp
int num = /* Initialize num with a value between 2 and 12 */;

if (num == 7 || num == 11)
{
    Console.WriteLine("Game status is WON");
}
else
{
    if (num == 2 || num == 3 || num == 12)
    {
        Console.WriteLine("Game status is LOST");
    }
    else
    {
        Console.WriteLine("Game status is CONTINUE");
    }
}
```

### Step-by-Step Explanation

1. **Condition Check for "WON"**:
    - The first if condition checks if `num` is either 7 or 11.
    - If true, it prints "Game status is WON".

2. **Condition Check for "LOST"**:
    - If the first condition is false, the program executes the else block.
    - Within this else block, another if statement checks if `num` is either 2, 3, or 12.
    - If true, it prints "Game status is LOST".

3. **Condition Check for "CONTINUE"**:
    - If none of the above conditions are satisfied, the final else block is executed.
    - This else block catches values of `num` that are 4, 5, 6, 8, 9, or 10.
    - It prints "Game status is
