### Educational Content on Arrays: Function for Column Maximums

**Task Description:**

Write a function `column_maxes` described as follows:

- **Parameters:**
  1. An N by N 2D array of integers (where N is given in the second parameter).
  2. An integer value for N that specifies the size of the array.

- **Functionality:**
  - Dynamically allocate a 1D array with N integers.
  - Populate this 1D array with the maximum values from the corresponding columns of the 2D array:
    - Entry 0 in the 1D array will store the maximum of column 0 from the 2D array.
    - Entry 1 in the 1D array will store the maximum of column 1 from the 2D array.
    - And so on...
  - Return the 1D array.

**Notes:** 
- You may write helper functions if you like.

**Example:**

Below is a 4x4 matrix of integers followed by the corresponding contents of the array you would allocate and populate:

```
Matrix:
12   102   9  -12
 8   -99  44   -3
16    12  12    0
13    18  -3   -8
```

**Array of Column Maximums:**

```
[16, 102, 44, 0]
```

This representation highlights how the function takes a matrix input and outputs an array containing the maximum value from each column.
