100% to find no. of elements in the array

//program to know how many numbers are there in the array

#include <stdio.h>
void main( )
{
    int n,p=50,no_of_bytes,packets[ ]={9,-1,7,4,5,11,8,4};
    no_of_bytes=sizeof(packets);
    n= no_of_bytes/sizeof(p);

    printf("\n the memory occupied by the array=%d",no_of_bytes);
    printf("\n number of elements in array=:%d",n);
}
