[编程入门]自定义函数之字符提取(c语言)

解题思路:

注意事项:

参考代码:

#include<stdio.h>

#include<string.h>

int fun(char x[],char b[])

{

        int n,l,j=0;

        l=strlen(x);

        for(n=0;n<l;n++)

        {

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

            {

               b[j]=x[n];

                j++;

            }

        }

        b[j]='\0';

        return 0;

}

int main()

{

        int x[100],b[100];

        gets(x);

        fun(x,b);

        puts(b);

        return 0;

}
