C#: Check whether a given number is within 2 of a multiple of 10
Within 2 of Multiple of 10
Write a C# Sharp program to check whether a given number is within 2 of a multiple of 10.
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(3)); // Output: True
Console.WriteLine(test(7)); // Output: True
Console.WriteLine(test(8)); // Output: True
Console.WriteLine(test(21)); // Output: False
Console.ReadLine(); // Keeping the console window open
}
// Method to check if the last digit of a number is less than or equal to 2 or greater than or equal to 8
public static bool test(int n)
{
// Returns true if the last digit of 'n' is less than or equal to 2 OR greater than or equal to 8
return n % 10 <= 2 || n % 10 >= 8;
}
}
}
Sample Output:
False False True True
