Find frequency of each word in a string in C#
To find the frequency of each word in a string, you can try to run the following code −
Example
using System; class Demo { static int maxCHARS = 256; static void calculate(String s, int[] cal) { for (int i = 0; i < s.Length; i++) cal[s[i]]++; } public static void Main() { String s = "Football!"; int []cal = new int[maxCHARS]; calculate(s, cal); for (int i = 0; i < maxCHARS; i++) if(cal[i] > 1) { Console.WriteLine("Character "+(char)i); Console.WriteLine("Occurrence = " + cal[i] + " times"); } } }
Output
Character l Occurrence = 2 times Character o Occurrence = 2 times
Above, we have set a string and an integer array. This helps us in getting the repeated values. The method calculates −
static void calculate(String s, int[] cal) { for (int i = 0; i < s.Length; i++) cal[s[i]]++; }
The value are then printed that shows the duplicate elements as well −
for (int i = 0; i < maxCHARS; i++) if(cal[i] > 1) { Console.WriteLine("Character "+(char)i); Console.WriteLine("Occurrence = " + cal[i] + " times"); }
