Test s for prime or not?


#include<stdio.h>
void main(void)
{
           int no,rem,cnt;
        Printf("enter No");
        scanf("%d",&no);
        cnt=2;
        while(cnt<=no)
       {

              rem=no % cnt;
              if (rem==0)
              {
              printf("No is not prime");
              exit(0);
              }
              cnt++;
        }
          printf("No is Prime");
}

A relation schema R is in 3NF if it is in 2NF and for every FD X A either of the following is true

Ø X is a Super-key of R.

Ø A is a prime attribute of R.

A relation schema R is in 2NF if it is in 1NF and every non-prime attribute A in R is fully functionally dependent on primary key.

AB -> B

AC -> C

C -> B

a) is in 1NF

b) is in 2NF

c) is in 3NF

d) is in BCNF

(a) is in 1NF since (AC)+ = { A, B, C} hence AC is the primary key. Since C B is a FD given, where neither C is a Key nor B is a prime attribute, this it is not in 3NF. Further B is not functionally dependent on key AC thus it is not in 2NF. Thus the given FDs is in 1NF.

cyclic redundancy check. Error-checking technique in which the frame recipient calculates a remainder by dividing frame contents by a prime binary divisor and compares the calculated remainder to a value stored in the frame by the sending node.

Like a Java Virtual Machine, the CLR removes the burden of memory management from developers by destroying objects once they are no longer being referenced. Before an object is removed from memory, it must free any resources it has allocated during its lifetime. In C++, this "cleanup code" is usually housed in an object's destructor, whereas in VB it is placed in the Class Terminate () method. Under the .NET Framework, cleanup code must reside in an object's Finalize () method, which is called just before the object is garbage-collected by the CLR. Finalize () is a method in the System.Object class from which all other .NET classes derive. You only have to override this method when you have cleanup code that should be performed before the class is destroyed. For performance reasons, the Finalize () method should only be employed when efficiently freeing a particular resource is a prime concern.

Group of communications products (including a protocol suite) developed and supported by Digital Equipment Corporation. DECnet/OSI (also called DECnet Phase V) is the most recent iteration and supports both OSI protocols and proprietary Digital protocols. Phase IV Prime supports inherent MAC addresses that allow DECnet nodes to coexist with systems running other protocols that have MAC address restrictions.
