自定义函数之字符提取

解题思路:

注意事项:

参考代码:

#include<stdio.h>

#include<string.h>

void copy(char a[], char b[])

{

int length,j=0;

length = strlen(a);

for (int i = 0;i < length;i++)

{

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

{

b[j] = a[i];

j++;

}

}

b[j] = '\0';

}

int main()

{

char a[100], b[100];

gets(a);

copy(a, b);

puts(b);

}
