C++ 实例 - 判断元音/辅音

我感觉题目所给的标准答案是可以再优化的

#include <iostream>
#include<ctype.h>
using namespace std;

int main()
{
    char world;
    char c[10];
    bool isChar;
    cout << "请输入一个字母" << endl;
    cin.get(c, 10);
    if (strlen(c) > 1)
    {
        cout << "请输入一个字符而不是字符串" << endl;
        return 0;
    }
    world = c[0];
    isChar = ((world >= 'a' && world <= 'z') || (world >= 'A' && world <= 'Z'));
    if (isChar) {
        if (world == 'a' || world == 'e' || world == 'i' || world == 'o' || world == 'u' || world == 'A' || world == 'E' || world == 'I' || world == 'O' || world == 'U') {
            cout << world << "该字母为元音" << endl;
            return 0;
        } else {
            cout << world << "该字母为辅音" << endl;
            return 0;
        }
    }
    cout << "不是字母" << endl;
    return 0;
}
