HDOJ 2027 统计元音

        统计输入的字符串中元音字母出现的次数，分别统计记数就好。

#include <cstdio>#include <cctype>const int MAX_SIZE = 100 + 2;char str[MAX_SIZE];//#define yangyuanint main(){#ifdef yangyuanfreopen("in.txt", "r", stdin);#endif // yangyuan    int n;    scanf("%d", &n);    getchar();// 读取末尾的换行符'\n'    int a, e, i, o, u;    while (n--){fgets(str, MAX_SIZE, stdin);a = e = i = o = u = 0;        for (int k = 0 ; k < MAX_SIZE && str[k] != '\n' && str[k] != '\0'; ++k){            switch (tolower(str[k]))            {case 'a':                a++;break;case 'e':e++;break;case 'i':i++;break;case 'o':o++;break;case 'u':u++;break;            }}        printf("a:%d\n", a);        printf("e:%d\n", e);        printf("i:%d\n", i);        printf("o:%d\n", o);        printf("u:%d\n", u);        if (0 != n)printf("\n");}    return 0;}
