C# 程序计算字符串中元音和辅音的个数


需要同时检查元音和辅音,但不要忘记检查大写和小写字母。

对于计算元音,分别检查 “aeiou” 字符,即

if (myStr[i] == 'a' || myStr[i] == 'e' || myStr[i] == 'i' || myStr[i] == 'o' || myStr[i] == 'u' || myStr[i] == 'A' || myStr[i] == 'E' || myStr[i] == 'I' || myStr[i] == 'O' || myStr[i] == 'U') {
   vowel_count++;
}

对于计算辅音,在 elseif 条件中检查其他字符,即 -

else if ((myStr[i] >= 'a' &amp;&amp; myStr[i] <= 'z') || (myStr[i] >= 'A' &amp;&amp; myStr[i] <= 'Z')) {
   cons_count++;
}

示例

以下是计算字符串中元音和辅音数量的代码。

using System;
public class Demo {
   public static void Main() {
      string myStr;
      int i, len, vowel_count, cons_count;
      myStr = "Jack Sparrow";
      vowel_count = 0;
      cons_count = 0;
      // find length
      len = myStr.Length;
      for(i=0; i<len; i++) {
         if(myStr[i] =='a' || myStr[i]=='e' || myStr[i]=='i' || myStr[i]=='o' || myStr[i]=='u' || myStr[i]=='A' || myStr[i]=='E' || myStr[i]=='I' || myStr[i]=='O' || myStr[i]=='U') {
            vowel_count++;
         } else if((myStr[i]>='a' &amp;&amp; myStr[i]<='z') || (myStr[i]>='A' &amp;&amp; myStr[i]<='Z')) {
            cons_count++;
         }
      }
      Console.Write("
Vowel in the string: {0}
", vowel_count);       Console.Write("Consonant in the string: {0}

", cons_count);    } }

输出

Vowel in the string: 3
Consonant in the string: 8
