Last update on June 25 2025 13:03:55 (UTC/GMT +8 hours)

Sum in Range 10-20 Returns 30

Write a C# Sharp program to compute the sum of the two given integers. If the sum is in the range 10..20 inclusive return 30.

Sample Solution:-

C# Sharp Code:

using System;
using System.Linq;

namespace exercises
{
    // Class declaration
    class Program
    {
        // Main method - entry point of the program
        static void Main(string[] args)
        {
            // Calling the 'test' method with different integers and printing the results
            Console.WriteLine(test(12, 17));   // Output: 30
            Console.WriteLine(test(2, 17));    // Output: 19
            Console.WriteLine(test(22, 17));   // Output: 30
            Console.WriteLine(test(20, 0));    // Output: 30
            Console.ReadLine(); // Keeping the console window open
        }

        // Method to check the sum of two integers and return a specific value based on conditions
        public static int test(int a, int b)
        {
            // Check if the sum of 'a' and 'b' is between 10 and 20 (inclusive)
            // If true, return 30; otherwise, return the actual sum of 'a' and 'b'
            return a + b >= 10 && a + b <= 20 ? 30 : a + b;
        }
    }
}
