Visual Presentation:
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 with different integers and displaying the returned boolean values
Console.WriteLine(test(3)); // Output: True
Console.WriteLine(test(14)); // Output: True
Console.WriteLine(test(12)); // Output: True
Console.WriteLine(test(37)); // Output: False
Console.ReadLine(); // Keeping the console window open
}
// Method to check if an integer is divisible by 3 or 7
public static bool test(int n)
{
// Returns true if the input integer is divisible by 3 or 7
return n % 3 == 0 || n % 7 == 0;
}
}
}
Sample Output:
True True True False
