<span>Clients depend on a working main server to perform their jobs: no, p2p relies on a structure without a central server.
</span><span>Individuals can easily add or remove devices from their network: yes, this is true.
</span><span>Requires an IT professional, but easy to add clients to server and give privileges: no, in p2p, the server doesn't play a role.
</span>
<span>Software is maintained on the server, allowing for easy access to upgrade programs for all users: this is not an aspect of p2p</span>
I think the first problem is B. and the second problem is D.
Answer:
The following are the code in the C++ Programming Language.
//define header file
#include <iostream>
// using namespace
using namespace std;
//define a class
class Accumulator
{
//set private access modifier
private:
//declare integer type variable
int sum;
//set public access modifier
public:
//define constructor
Accumulator (int sum)
{
//refer the same class as instance variable
this->sum = sum;
}
//define integer type function
int getSum()
{
//return the value of sum
return sum;
}
//define void type function
void add (int value)
{
//variable sum is increased by the argument value
sum += value;
}
};
Explanation:
<u>The following are the description of the code</u>.
- Firstly, set the required header file and namespace then, define a class 'Accumulator' and inside the class.
- Set private access modifier then, declare an integer data type variable 'sum'.
- Declare a class constructor whose name is the same as the class name 'Accumulator()' and pass integer data type argument 'sum' in its parameter that refers to the same class as instance variable.
- Define a integer data type function 'getSum()' that return the value of the variable sum.
- Finally, define a void type function 'add()' and pass the integer data type argument 'value' in its parameter in which the variable sum is increased by the argument value
