Letter Frequency Test

A C# program that analyzes character frequency in text files and displays them in descending order of occurrence.

Overview

This script reads a text file (in this case, harry-potter.txt) and counts the occurrences of each character, then outputs the results sorted by frequency from most to least common.

Requirements

• .NET SDK (10.0 or later recommended)
• A text file named harry-potter.txt in the same directory as the script

Usage

Run the script using the dotnet script runner:

dotnet LetterFrequencyTest.cs

Or make it executable:

chmod +x LetterFrequencyTest.cs
./LetterFrequencyTest.cs

Output Format

The script outputs each character with its rank and occurrence count:

# 1 - char: [space] - occurrences: 150000
# 2 - char: e - occurrences: 95000
# 3 - char: t - occurrences: 70000
