自定义函数之字符提取(所有人都看得懂)

解题思路:

注意事项:

参考代码:

#include<stdio.h>

int main()

{

char str[100];

char a[100];

int count = 0;

scanf("%s", &str);

int i = 0;

int size = sizeof(str) / sizeof(str[0]);

for (i = 0; i < size; i++)

{

if (str[i] == 'a' || str[i] == 'e' || str[i] == 'i' || str[i] == 'o' || str[i] == 'u')

{

a[count] = str[i];

count++;

}

}

int j = 0;

for (j = 0; j < count; j++)

{

if(a[j]=='a')

printf("%c", a[j]);

}

for (j = 0; j < count; j++)

{

if (a[j] == 'e')

printf("%c", a[j]);

}

for (j = 0; j < count; j++)

{

if (a[j] == 'i')

printf("%c", a[j]);

}

for (j = 0; j < count; j++)

{

if (a[j] == 'o')

printf("%c", a[j]);

}

for (j = 0; j < count; j++)

{

if (a[j] == 'u')

printf("%c", a[j]);

}

}
