C++如何使用find函数在char数组中查找char？

Question

如何使用find函数在char数组中查找char？如果我只是为了循环元音然后我可以得到答案但我被要求使用std :: find ..谢谢.

bool IsVowel (char c) { 

    char vowel[] = {'a', 'e', 'i', 'o', 'u'};            
    bool rtn = std::find(vowel, vowel + 5, c);

    std::cout << " Trace : " << c  << " " << rtn << endl;

    return rtn; 
 }

Answer 1

bool IsVowel (char c) { 

    char vowel[] = {'a', 'e', 'i', 'o', 'u'};
    char* end = vowel + sizeof(vowel) / sizeof(vowel[0]);            
    char* position = std::find(vowel, end, c);

    return (position != end); 
 }
