C#: Calculate the average word length in a string
C# Sharp Regular Expression: Exercise-2 with Solution
Write a C# Sharp program to calculate the average word length in a given string. Round the average length up to two decimal places.
Note: Ignore punctuation.
Sample Data:
("CPP Exercises." -> 6
("C# syntax is highly expressive, yet it is also simple and easy to learn.") -> 4
(“C# is an elegant and type-safe object-oriented language") -> 5.62
Sample Solution-1:
C# Sharp Code:
using System;
using System.Text.RegularExpressions;
using System.Linq;
namespace exercises
{
class Program
{
static void Main(string[] args)
{
string text = "CPP Exercises.";
Console.WriteLine("Original string: " + text);
Console.WriteLine("The average word length in the said string: " + test(text));
text = "C# syntax is highly expressive, yet it is also simple and easy to learn.";
Console.WriteLine("Original string: " + text);
Console.WriteLine("The average word length in the said string: " + test(text));
text = "C# is an elegant and type-safe object-oriented language";
Console.WriteLine("Original string: " + text);
Console.WriteLine("The average word length in the said string: " + test(text));
}
public static double test(string text)
{
string new_text = Regex.Replace(text, "[^A-Za-z ]", "");
double average_len = new_text.Split(' ').Select(x => x.Length).Average();
return Math.Round(average_len, 2);
}
}
}
Sample Output:
Original string: CPP Exercises. The average word length in the said string: 6 Original string: C# syntax is highly expressive, yet it is also simple and easy to learn. The average word length in the said string: 4 Original string: C# is an elegant and type-safe object-oriented language The average word length in the said string: 5.62

Sample Solution-2:
C# Sharp Code:
using System;
using System.Text.RegularExpressions;
using System.Linq;
namespace exercises
{
class Program
{
static void Main(string[] args)
{
string text = "CPP Exercises.";
Console.WriteLine("Original string: " + text);
Console.WriteLine("The average word length in the said string: " + test(text));
text = "C# syntax is highly expressive, yet it is also simple and easy to learn.";
Console.WriteLine("Original string: " + text);
Console.WriteLine("The average word length in the said string: " + test(text));
text = "C# is an elegant and type-safe object-oriented language";
Console.WriteLine("Original string: " + text);
Console.WriteLine("The average word length in the said string: " + test(text));
}
public static double test(string text)
{
return Math.Round((double)text.Where(ch => char.IsLetter(ch)).Count() / (double)(text.Where(ch => char.IsWhiteSpace(ch)).Count() + 1), 2);
}
}
}
Sample Output:
Original string: CPP Exercises. The average word length in the said string: 6 Original string: C# syntax is highly expressive, yet it is also simple and easy to learn. The average word length in the said string: 4 Original string: C# is an elegant and type-safe object-oriented language The average word length in the said string: 5.62
