C语言计算字符中元音个数示例

在C语言中，如何计算字符中的元音字符个数？创建一个源文件：program_to_count_vowels_in_string.c，参考以下实现代码 -

#include <stdio.h>

int main() {
    char s[] = "xuhuhu.com";     // String Given
    int i = 0;
    int vowels = 0;            // Vowels counter
    int consonants = 0;        // Consonants counter

    while (s[i++] != '\0') {
        if (s[i] == 'a' || s[i] == 'e' || s[i] == 'i' || s[i] == 'o' || s[i] == 'u')
            vowels++;
        else
            consonants++;
    }

    printf("'%s' contains %d vowels and %d consonants.\n", s, vowels, consonants);

    return 0;
}

执行上面示例代码，得到以下结果 -

'xuhuhu.com' contains 5 vowels and 5 consonants.
