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' && myStr[i] <= 'z') || (myStr[i] >= 'A' && 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' && myStr[i]<='z') || (myStr[i]>='A' && 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
