Compare number within a numerical range

Question

I want to create a function that receives a number and check if it is within a range from 1 to 25. What is the best way to do this?

private int VerificaIntervalo(int numero)
{
    if (numero > 25)
    {
        return 0;
    }
    return 1;
}

Answer 1

It’s much simpler than other options:

private bool VerificaIntervalo(int numero) => numero >= 1 && numero <= 25;

I put in the Github for future reference.

Ideally the name of the method could be more explanatory than refers to this.

Answer 2

the simplest would be:

private bool VerificaIntervalo(int numero)
{
   if(numero >= 1 && numero <= 25)
     return true;
   else
     return false;
}

Answer 3

Here an example for you to check if the numbers are in the range 1 to 25, see below:

using System;

public class Test
{
    public static void Main()
    {
        if (comparaNumero(90))
           Console.WriteLine("Dentro do intervalo entre 1 a 25");
        else
           Console.WriteLine("Fora do intervalo");
    }

    public static bool comparaNumero(int n)
    {
        return (n >= 1 && n <= 25);
    }
}

See worked on Ideone.

Answer 4

private bool VerificaIntervalo(int numero)
    {
          if(numero >= 1 && numero <= 25)
          {
            return true;
          }
          else
          {
           return false;
          }
    }

Would that be?
