Answer:
The answer to this question is given below in this explanation section.
Explanation:
In the relationship model of database a primary key is a specific choice of a minimal set of attributes that uniquely specific a tuple in a relation.Informally a primary key is which attribute and in simple cases are simple a single attribute.More formally a primary key is a choice of candidate key any other candidate key is an alternate key.
A primary key may consists of real word observable in which way it is called natural key,while an attribute created to function as a key and not use for identification outside the database is called a surrogate key.For example for a database of people time and location of birth could be a natural key.National identification number is another example of an attribute that may be used as an natural key.

Explanation:
Vector Multiplication code:
Vector_multiplication.c file contains C code.
See attachment no 1 attached below
Classification of Algorithm: For creating elements in vector c of size n, number of scalar multiplications is equal to n. The size of original two vectors scales directly with the number of operations. Hence, it is classified as O(n).
<span>One emerging type of Trojan horse is called a remote-access Trojan (RAT).
</span> RAT is a malware program. With this Trojan horse an intruder is given administrative control over a target computer. The RAT controls the system via a remote network connection as if by physical access. It is typically installed<span> invisibly with a user-requested program.</span>
The code statement that completes the program is total_coins = nickel_count + dime_count
<h3>How to complete the segment?</h3>
From the code segment, we have the following highlights:
- total_coins is initialized to 0, at line 1
- Inputs for nickel_count and dime_count are taken on lines 2 and 3
- The last line prints total_coins
The above means that total_coins has not been calculated.
This is calculated using:
total_coins = nickel_count + dime_count
The above must be placed before the last line of the program

<h3>Complete question</h3>
Complete the code segment to calculate the total number of coins
total_coins = 0
nickel_count = int(input())
dime_count = int(input())
print(total_coins)
