Function returning a value - 2

Proposed exercise

---

Create a program whose Main must be like this:

public static void Main()

{
Console.WriteLine("\"Hello, how are you\" contains {0} spaces",

    CountSpaces("Hello, how are you") );

}

CountSpaces is a function that you must define and that will be called from inside Main.

As you can see in the example, it must accept an string as a parameter, and it must return an integer number (the amount of spaces in that string).

Output

Solution

---

using System;
public class CountSpacess
{
public static int CountSpaces(string text)
{   
int countSpaces=0;
string letter;
for (int i = 0;i < text.Length;i++)
{
letter = text.Substring(i,1);
if (letter == " ")
countSpaces++;
}
return countSpaces;
}

public static void Main()
{
Console.WriteLine("\"Hello, how are you\" contains {0} spaces",
CountSpaces("Hello, how are you") );
}    
}
