Answer:
// A optimized school method based C++ program to check
// if a number is composite.
#include <bits/stdc++.h>
using namespace std;
bool isComposite(int n)
{
// Corner cases
if (n <= 1) return false;
if (n <= 3) return false;
// This is checked so that we can skip
// middle five numbers in below loop
if (n%2 == 0 || n%3 == 0) return true;
for (int i=5; i*i<=n; i=i+6)
if (n%i == 0 || n%(i+2) == 0)
return true;
return false;
}
// Driver Program to test above function
int main()
{
isComposite(11)? cout << " true\n": cout << " false\n";
isComposite(15)? cout << " true\n": cout << " false\n";
return 0;
}
Explanation:
If this is the full question " <span>Which of the following formulas is equivalent to =SUM(A1:A3)?
A. =A1+A3
B. =A1+A2+A3
B. =A2
D. =A3-A1"
The answer is </span>
<span>B. =A1+A2+A3 formulas is equivalent to =SUM(A1:A3)</span>
Answer:
Data manipulation languages are used for the retrieval of the,insertion,deletion and modification of data.
Explanation:
Data Manipulation Languages(DML) are used to insert,delete,update,modify the data in the database.
The commands used to do these operations are as following:-
INSERT INTO :-This command is used to insert values in the database.
DELETE:-It is used to delete existing records from the table.
UPDATE:- It is used to modify the records in the table.
SELECT:- It is used to select data from database.
Answer:
Option (C) FAT32 File System Type
Explanation:
- FAT32 File System Type cannot be encrypted by the accounting users.
- FAT stands for File Allocation Table. It is a file system architecture.
- The File Allocation Table is an index table which contains the details about each cluster ( disk storage space ).
- By traversing the File Allocation Table, the operating system gets the details the file ( where it is located ) and the size of the file.
- The FAT32 file system contains more number of possible clusters.
- In this system, 32 bits are used to store the total number of possible clusters.
- In FAT32 file system, the transparent encryption is not supported.
- So, option (C) is correct.
- All other options are wrong options.
