Check Within 20 of 100 or 200

Write a C# program to check if the given integer is within 20 of 100 or 200.

Sample Solution:-

C# Sharp Code:

using System;
using System.Collections.Generic;

// This is the beginning of the Exercise22 class
public class Exercise22 {
    // This is the main method where the program execution starts
    static void Main(string[] args) {
        Console.WriteLine("\nInput an integer:"); // Prompting the user to input an integer
        int x = Convert.ToInt32(Console.ReadLine()); // Reading the integer input provided by the user

        Console.WriteLine(result(x)); // Calling the 'result' method and printing the result
    }

    // Method to check if the given integer is within 20 units of 100 or 200
    public static bool result(int n) {
        // Checking if the absolute difference between 'n' and 100 is less than or equal to 20
        // OR the absolute difference between 'n' and 200 is less than or equal to 20
        if (Math.Abs(n - 100) <= 20 || Math.Abs(n - 200) <= 20)
            return true; // Return true if the condition is satisfied
        return false; // Return false if the condition is not satisfied
    }
}

Sample Output:

Input an integer: 25                                                                     
False

Sample Output:

Input an integer: 50
False

Sample Output:

Input an integer: 70
False

Sample Output:

Input an integer: 80
True

Sample Output:

Input an integer: 90
True

Sample Output:

Input an integer: 110
True

Sample Output:

Input an integer: 120
True

Sample Output:

Input an integer: 125
False

Sample Output:

Input an integer: 130
False

Previous: Write a C# program to check the sum of the two given integers and return true if one of the integer is 20 or if their sum is 20.
Next: Write a C# program to convert a given string into lowercase.
