请c语言的高手给编一个程序

int removeDup(int list[],int listSize)
{
int i,j,temp,k;
for(i = 0;i < listSize;i++)
{
temp = list[i];
for(j = i + 1;j < listSize;j++)
{
if(temp == list[j])
{
/* cover the duplicated element */
for(k = i;k < listSize - 1;k++)
list[k] = list[k + 1];
listSize--;
}
}
}
return j;
}
int main()
{
int list[] = {1,2,3,3,4,0};
int ret = removeDup(list,6);
printf("count = %d\n",ret);
for (int i=0;i<ret;i++)
{
printf("%d\n",list[i]);
}
return 0;
}

#include <stdio.h>

// print all element
void print(int arr[], int len)
{
int i;
for (i=0; i<len; ++i)
printf("%d ", arr[i]);
printf("\n");
}
