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++; } }
You can try to run the following code to count the occurrences of each character.
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(); } }
String: Website W = 1 e = 2 b = 1 s = 1 i = 1 t = 1
