Write a program in C# Sharp to create a function to input a string and count the number of spaces within the string.

Sample Solution:

C# Sharp Code:

using System;

// Define a public class named 'funcexer4'
public class funcexer4
{
    // Define a public static method 'SpaceCount' that counts spaces in a string and returns the count
    public static int SpaceCount(string str)
    {   
        // Initialize a counter for spaces
        int spcctr = 0;
        string str1;

        // Loop through each character in the string
        for (int i = 0; i < str.Length; i++)
        {
            // Extract each character individually
            str1 = str.Substring(i, 1);

            // Check if the character is a space, if true, increment the space counter
            if (str1 == " ")
                spcctr++;
        }

        return spcctr; // Return the total count of spaces in the string
    }

    // Main method, the entry point of the program
    public static void Main()
    {
        string str2;

        // Print a description of the program
        Console.Write("\n\nFunction to count number of spaces in a string :\n");
        Console.Write("----------------------------------------------------\n");

        // Prompt the user to input a string and read the input
        Console.Write("Please input a string : ");
        str2 = Console.ReadLine();

        // Call the 'SpaceCount' method and print the count of spaces in the input string
        Console.WriteLine("\"" + str2 + "\"" + " contains {0} spaces", SpaceCount(str2));
    }    
}

Sample Output:

Function to count number of spaces in a string :                       
----------------------------------------------------                   
Please input a string : w3resource is a tutorial                       
"w3resource is a tutorial" contains 3 spaces
