Sum of Two Numbers

Write a C# Sharp program to print the sum of two numbers.

In mathematics, summation (capital Greek sigma symbol: ∑) is the addition of a sequence of numbers; the result is their sum or total. The numbers to be summed may be integers, rational numbers, real numbers, or complex numbers.

Sample Solution:

C# Sharp Code:

// This is the beginning of the Exercise2 class
public class Exercise2
{
    // This is the main method where the program execution starts
    public static void Main()
    {
        // This line performs addition of 15 and 17 and outputs the result to the console
        System.Console.WriteLine(15 + 17);
    }
}

Sample Output:

32
