C#程序统计每个字符的出现
首先,设置字符串-
string str = "Website"; Console.WriteLine("String: "+str);
检查字符串中的每个字符,并增加一个变量,该变量将计算该字符的出现次数-
for (int j = 0; j < str.Length; j++) { if (str[0] == str[j]) { cal++; } }
示例
您可以尝试运行以下代码来计算每个字符的出现次数。
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(); } }
输出结果
String: Website W = 1 e = 2 b = 1 s = 1 i = 1 t = 1
