C# Find the addition of two integer numbers

Example:

    Input:
    First number: 10
    Second number: 20

    Output:
    Addition of 10 and 20 is = 30

Program:

using System;
class AddTwoNumbers {
    static void Main() {
        try{
            //declare two variables
            int a = 0;
            int b = 0;
            
            //input numbers
            Console.Write("Enter first number: ");
            a = Convert.ToInt32(Console.ReadLine());
            Console.Write("Enter second number: ");
            b = Convert.ToInt32(Console.ReadLine());            
            
            //calculating sum
            int sum = a+b;
            
            Console.WriteLine("Addition of " + a + " and " + b + " is = " + sum);
        }
        catch(Exception ex){
            Console.WriteLine("Error: " + ex.ToString());
        }
    }
}

Output

Enter first number: 10
Enter second number: 20
Addition of 10 and 20 is = 30

Program:

using System;
class AddTwoNumbers {
    //defining function
    static int sumOfTwoNumber(int x, int y){
        return x+y;
    }
    //main function
    static void Main() {
        try{
            //declare two variables
            int a = 0;
            int b = 0;
            
            //input numbers
            Console.Write("Enter first number: ");
            a = Convert.ToInt32(Console.ReadLine());
            Console.Write("Enter second number: ");
            b = Convert.ToInt32(Console.ReadLine());            
            
            //calculating sum by calling the function
            int sum = sumOfTwoNumber(a,b);
            
            Console.WriteLine("Addition of " + a + " and " + b + " is = " + sum);
        }
        catch(Exception ex){
            Console.WriteLine("Error: " + ex.ToString());
        }
    }
}

Output

Enter first number: 10
Enter second number: 20
Addition of 10 and 20 is = 30
