#Write a function called is_composite. is_composite should #take as input one integer. It should return True if the #integer is

composite, False if the integer is not not #composite. You may assume the integer will be greater than #2 and less than 1000.

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;  

}

What is the disadvantage of a mesh topology?
-BARSIC- [3]

Answer:

Topology means arrangement of nodes

Explanation:

In computer science the word topology means the arrangement of nodes and elements in a network. For any topology we do need nodes and cables for maintaining the infrastructure.

In mesh topology the all nodes use to get connected by direct link. While each and every node is directly associated with  one another. In this infrastructure we do need lot cabling where every node will be connected with one another. While usage of good quality cable in network is  also expensive to manage. Although there are lot of benefits of this topology, where the transmission of data would never stop if node is not working the rest will be working to transfer the data among other nodes ,this is more secure because there is no traffic for data to travel via many nodes   to reach the destination. Every node is directly connected and communicate. So, once the node is not working the communication will not be stop but the maintenance and troubleshooting will be difficult in this infrastructure.

It is proved along with lot of benefits and network security ,this infrastructure is having some disadvantages as well. Cabling expense , maintenance cost etc  . usually small scale networks do not prefer mesh topology.  Small scale and low budget companies can  not afford this topology because it is expensive.

Although we do believe that the data security is most important for today's era ,so few companies those wanted to keep their information secure and confidential they must use mesh topology by ignoring the cost incurred for this set up. Data security and integrity would never be compromised by some of the companies.

Mesh topology is more safer, more quick infrastructure which is although very expensive , difficult to mange and maintain. Moreover it is overhead of cabling as well to connect every node but the demand of mesh topology would never be less. It is demanding and appealing topology still.

c++ Write a statement that increments (adds 1 to) one and only one of these five variables: reverseDrivers parkedDrivers slowDri
Mazyrski [523]

Answer:

The following statement are:

if(speed < 0) // if statement

{

reverseDrivers++; //if the speed is less than 0, then increment in "reverseDrivers"

}

else if(speed < 1) //else if statement

{

parkedDrivers++; //speed is less than 1, than increments in "parkedDrivers"

}

else if(speed < 40)

{

slowDrivers++; //speed is less then 40, than increment in "slowDriver"

}

else if(speed <= 65)

{

safeDrivers++; //speed is less than or equal to 40, then increment in "safeDriver"

}

else

{

speeders++; //else increment in speeders

}

Explanation:

From the following statement their are certain condition arises

If the speed is less than 0, then increments the “reverseDrivers” variable by 1.

If the speed is less than 1, then increments the “parkDriver” variable by 1.

If speed is less than 40, then increment in "slowDriver" variable by 1.

If speed is less than or equal to 40, then increment in "safeDriver" variable by 1.

Otherwise increment in "speeders"

miss Akunina [59]
A pure aggregator is best defined as a blog that aggregates blog content from other sources.

An Aggregator blog or website don't write its own content. It aggregates information or content from third-party websites. There are different types of aggregator websites such as a poll aggregator, a review aggregator, and a search aggregator.
