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 = "Welcometomywebsite!"; int []cal = new int[maxCHARS]; calculate(s, cal); for (int i = 0; i 1) { Console.WriteLine("Character "+(char)i); Console.WriteLine("Occurrence = " + cal[i] + " times"); } } }登录后复制
