# 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
```
