DECLARE Marks as an array of integers with size 10
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...
```
To declare an array named "Marks" of integers with a size of 10, you can use the following code in various programming languages:
1. C++:
```cpp
int Marks[10];
```
2. Java:
```java
int[] Marks = new int[10];
```
3. Python:
```python
Marks = [0] * 10
```
4. C#:
```csharp
int[] Marks = new int[10];
```
5. JavaScript:
```javascript
let Marks = new Array(10);
```
6. Ruby:
```ruby
Marks = Array.new(10)
```
Please note that the syntax may vary slightly depending on the programming language you are using, but the concept remains the same.
