C#: Check a given integer and return true if it is within 10 of 100 or 200


Within 10 of 100 or 200

Write a C# Sharp program to check a given integer and return true if it is within 10 of 100 or 200.

Sample Solution:

C# Sharp Code:

using System;

// Namespace declaration
namespace exercises
{
    // Class declaration
    class Program
    {
        // Main method - entry point of the program
        static void Main(string[] args)
        {
            // Calling the 'test' method and displaying the returned boolean values
            Console.WriteLine(test(103));    // Output: True
            Console.WriteLine(test(90));     // Output: True
            Console.WriteLine(test(89));     // Output: False
            Console.ReadLine();              // Keeping the console window open
        }

        // Method to check if a given integer is within 10 units of 100 or 200
        public static bool test(int x)
        {
            // Checking if the absolute difference between 'x' and 100 is less than or equal to 10,
            // OR the absolute difference between 'x' and 200 is less than or equal to 10.
            // If either condition is true, returns true; otherwise, returns false.
            if (Math.Abs(x - 100) <= 10 || Math.Abs(x - 200) <= 10)
                return true;
            return false;
        }
    }
}

Sample Output:

True
True
False

  • Write a C# program to check if a number is within 5 units of 50 or 150, exclusive.
  • Write a C# program that returns true if the absolute distance from 100 or 200 is divisible by 10.
  • Write a C# program to return true if a number lies within 10% of either 100 or 200.
