Final answer:
To declare an object named "ar" from the Arithmetic class with two non-zero integer parameters, you create a new instance of the class with those integers passed to its constructor.
Step-by-step explanation:
To declare a class object named "ar" from the Arithmetic class with two integer parameters, you would typically write this in a programming language such as Java or C++. Since the language is not specified, I'll provide an example in Java:
Arithmetic ar = new Arithmetic(5, 10);
This line of code declares a new object "ar" of the class Arithmetic. The Arithmetic class must already be defined with a constructor that accepts two integer parameters. When creating "ar", we are initializing it by passing two non-zero integers to the constructor, such as 5 and 10 in the example above.
