Write code that causes a "triangle" of asterisks of size n to be output to the screen. specifically, n lines should be printed out, the first consisting of a single asterisk, the second consisting of two asterisks, the third consisting of three, etc. the last line should consist of n asterisks. thus, for example, if n has value 3, the output of your code should be

To solve this problem using programming, we'll assume you want a solution in Python. Below is a step-by-step Python code to print a triangle of asterisks with `n` as its size:

```python # Size of the triangle n = 3

# Loop through the number of lines for i in range(1, n + 1): # For each line, print the appropriate number of asterisks # The end="" keeps the print statement from starting a new line after printing print('*' * i) ```

When `n` is 3, as in the given example, the output of this code will be:

``` * ** *** ```

Extra: In the above example, the `range()` function generates a sequence of numbers from 1 to `n` (inclusive). On each iteration of the `for` loop, the variable `i` takes on the next value in this sequence. The inner `print('*' * i)` statement then prints `i` asterisks. Notice how we multiply a string (`'*'`) by an integer (`i`), which is a feature in Python that repeats the string `i` times.

In Python, the `print()` function by default ends with a newline character (`\n`), which moves the cursor to the beginning of the next line after printing. However, the default can be changed using the `end` parameter. In the code above, we use the default newline character each time as we want each row of asterisks to be on a new line.

When writing code like this, it is essential to think about how the output should look and how each line relates to the iteration of the loop. The pattern in this case is simple: the first line has one asterisk, the second line has two, and so on, until line `n` has `n` asterisks. This pattern is why the expression `'*' * i` works to generate the correct number of asterisks on each line.
