Option 1 is not correct as it will provide the list of all the customers whether they have placed order or not.
Option 2 is not correct as it will provide the list of customers who have placed order but are not in the customers table. This will return the empty records.
Option 3 is not correct as it will provide the list of customers who have placed the order.
Option 4 is correct as it will provide the list of customers from the CUSTOMERS table which are not in the Orders table. thus the list of customers who have not placed the order yet.

Answer:
#include <stdio.h>
void printValues ( unsigned char *ptr, int count) // count is no of cells
{
for(int i=0; i<count; i++) {
printf("%d ", ptr[i]);
}
}
int main ( )
{
unsigned char data[ ] = { 9, 8, 7, 5, 3, 2, 1} ;
printValues( data, sizeof(data)/sizeof(data[0]) );
}
Explanation:
Remember that the sizeof() mechanism fails if a pointer to the data is passed to a function. That's why the count variable is needed in the first place.
