请编写函数int funint a,int n,它的功能是把形参a所指数组中的偶数按原顺序依次存放到a0a1a2中,把奇数从数组中删除,偶数个数通过函数值返回,以-1作为有效数据的结束标志例若输入1

#include<stdio.h>
#define N 9
int fun (int a[], int n)
{
    
     
    int i, j;
    j=0;
    for (i=0; i<n; i++)
    /**********found**********/
    if (a[i]%2== 1)
    {
    
    
        /**********found**********/
        a[j]=a[i];   
        j++;
    }
    /**********found**********/
    return j;
}
main( )
{
    
     
    int b[N]={
    
    9,1,4,2,3,6,5,8,7}, i, n;
    printf("\nThe original data:\n");
    for(i=0; i<N; i++)
        printf("% 4d", b[i]);
    printf("\n");
    n=fun(b, N);
    printf("\nThe number of odd:% d\n", n);
    printf("\nThe odd number: \n");
    for(i=0; i<n; i++)
        printf("%4d",b[i]);
    printf("\n");
}
