how do i use EOF in a char array?

[mike81]

Hi,
I was hoping someone may be able to help me out.
I am trying to write a program which reads and prints an input of words.
It needs to hold a max of 10 words but i need use a sentinel contolled loop using the EOF (<ctrlZ> twice) so i can end it early if needed.
I have tried to use a while loop in scanf unsucessfully in the code below.

Any help would be greatly appreciated.
Cheers,
Mike.

#include <stdio.h>
#include <string.h>
main()
{
char word[10][100];
int a, x=0;


	for(a=0; a<10; a++)
		{
		printf("enter a word\n");
		scanf("%s", word[x]);
		x=x+1;
		}
		x=0;
		
	printf("the word list is:\n");	
	for(a=0; a<10; a++)
		{
		printf("%s\n", word[x]);
		x=x+1;
		}
}
