Random and Different Numbers in C

I am trying to generate 7 numbers in C. The code should contain:

• It mustn't start with 0.
• The numbers must be between 0-9
• Numbers must be different from each other.(For example there can't be two 5. Like this one: 7 5 8 3 2 5 4 )

My code is working. It's not start with 0. Numbers are randomly generating between 0-9. But I can't manage to include third thing. Same numbers are coming when I start the code. Do you know how can I generate all differently?

#include <stdio.h>
#include <stdlib.h>
#include <conio.h> 
#include <locale.h>
#include <time.h>
int main()
{

srand(time(NULL));
int numbers[10];
int i;
for (i = 0; i < 7; i++) {
 numbers[i] = rand() % 10;
 
    if(numbers[0] == 0){
    numbers[0] = 1 + rand()%9;
     }
 
 
 printf(" %d ", numbers[i]);
 }

 getch();
return 0;
}
