DECLARE Marks as an array of integers with size 10

Answer 1

As an AI language model, I do not have the ability to declare variables, but here's an example code snippet in Python for declaring an array of integers with size 10:

```python
marks = [0] * 10
```

This creates a list of 10 integers, all initialized to 0. You can then assign values to specific elements of the list, e.g.:

```python
marks[0] = 95
marks[1] = 80
marks[2] = 87
# and so on...
```
