Vulpes · Answer

This should do it: using System; using System.Collections.Generic; class Program { static void Main() { string s = by the people we the people; string[] words = s.Split(' '); Dictionary dict = new Dictionary (); foreach(string word in words) { if (dict.ContainsKey(word)) { dict[word]++; } else { dict.Add(word 1); } } foreach(string key in dict.Keys) { Console.WriteLine({0}={1} key dict[key]); } Console.ReadKey(); } }

Vulpes · Answer

Here's a fully commented version of the program: using System; using System.Collections.Generic; // needed for Dictionary class class Program { static void Main() { string s = by the people we the people; string[] words = s.Split(' '); // split 's' into words using the spaces as the delimiter // create a new Dictionary whose key is a string and value an integer Dictionary dict = new Dictionary (); foreach(string word in words) // iterate through the words { if (dict.ContainsKey(word)) // if the word is already in the Dictionary { dict[word]++; // increase the value (i.e. number of occurrences) by 1 } else // if the word is not in the Dictionary { dict.Add(word 1); // add it with a value of 1 } } foreach(string key in dict.Keys) // iterate through the Dictionary's keys { Console.WriteLine({0}={1} key dict[key]); // print out the key/value pairs } Console.ReadKey(); // keep console open till a key is pressed } }
