Count words, and skip the spaces.

Freddy Abreu

Hi, this something very basic I know it, but how can I skip the spaces in this basic program please.

            string Palabras = string.Empty;
            //int ContEspacios;



            Console.WriteLine("Escribe una palabra:");
            Palabras = Console.ReadLine();

            foreach (var X in Palabras.Length.ToString())
            {


                Console.WriteLine("Cuantas palabras tiene {0}:",X);
            }


            Console.Write("Press any key to continue . . . ");
            Console.ReadKey(true);
        }
    }
}

Counting words is something which is usually best done using the String.Split method or regular expressions but it can be done by iterating through the characters.

Try the following:

using System;

class Program
{
static void Main()
{
string Palabras = string.Empty;
//int ContEspacios;

Console.WriteLine("Escribe una palabra:");
Palabras = Console.ReadLine().Trim(); // get rid of any leading or trailing spaces

int wordCount = 0;
if (Palabras.Trim() != "")
{
bool lastCharWasSpace = false;
foreach (char X in Palabras)
{
if (X == ' ')
{
if (!lastCharWasSpace)
{
wordCount++;
lastCharWasSpace = true;
}
}
else
{
lastCharWasSpace = false;
}
}
wordCount++;
}

Console.WriteLine("Cuantas palabras tiene {0}:", wordCount);
Console.Write("Press any key to continue . . . ");
Console.ReadKey(true);
}
}

Thank you both for being patient and for answering my doubts, and actually know what ASCII code it is, but never imagined, you meant to that... hope everything go fine with both of you.

Blessings.

The ASCII (and Unicode) code for the space character is 32 and when you have a line like this:

if (s == 32)

then the char 's' is converted to its Unicode equvalent before making the comparison.

The reason why Sandeep's code is shorter than mine is because mine deals with the possibility that there could be multiple consecutive spaces between words.

Hey maybe I'm going to ask a Clumsy question But why if (s == 32)?
you mean 32 bits? right?
Forgive me for the ignorant question.

Hey Sandeep it works out perfectly! and it is shorter.
This is the best forum I've ever been before.

string Palabras = string.Empty;
//int ContEspacios;

Console.WriteLine("Escribe una palabra:");
Palabras = Console.ReadLine();
int ContEspacios = 0;

foreach (char s in Palabras)
{
if (s == 32)
{
ContEspacios++;
}
}
Console.WriteLine("Total Number of words : {0}", ++ContEspacios);

Console.Write("Press any key to continue . . . ");
Console.ReadKey(true);
