修改如下，供参考：

#include "stdio.h"
void ycopy(char x[], int n)
{ 
   
   char y[26]={0};
   int  i, j;
   //gets(x);
    for (i=j=0; i<n; i++){  // for (i=0, j=0;  i<n; i++,j++){
          if(x[i]=='a'||x[i]=='A'
           ||x[i]=='e'||x[i]=='E'
           ||x[i]=='i'||x[i]=='I'
           ||x[i]=='o'||x[i]=='O'
           ||x[i]=='u'||x[i]=='U')
           {
              y[j++]=x[i];
           }
        //else if (x[i]=='e'||x[i]=='E')
        //   {
        //      y[j]=x[i];
        //   }
        //else if (x[i]=='i'||x[i]=='I')
        //   {
        //      y[j]=x[i];
        //   }
        //else if (x[i]=='o'||x[i]=='O')
        //   {
        //      y[j]=x[i];
        //   }
        //else if(x[i]=='u'||x[i]=='U')
        //   {
        //      y[j]=x[i];
        //   }
   
    }
    y[j] = '\0';
    printf("%s",y);
}

int main()  //void main()
{

    char a[20]="asdfeiou";
    ycopy(a,20);

    return 0;
