C# program to count the occurrences of each character

Firstly, set the string −

string str = "Website"; Console.WriteLine("String: "+str);

Check for every character in the string and increment a variable that would count the number of occurrences of that character −

for (int j = 0; j < str.Length; j++) {    if (str[0] == str[j]) {       cal++;    } }

Example

You can try to run the following code to count the occurrences of each character.

Live Demo

using System; public class Demo {    public static void Main() {       string str = "Website";       Console.WriteLine("String: "+str);       while (str.Length > 0) {          Console.Write(str[0] + " = ");          int cal = 0;          for (int j = 0; j < str.Length; j++) {             if (str[0] == str[j]) {                cal++;             }          }          Console.WriteLine(cal);          str = str.Replace(str[0].ToString(), string.Empty);       }       Console.ReadLine();    } }

Output

String: Website W = 1 e = 2 b = 1 s = 1 i = 1 t = 1
