Design a class that has an array of floating-point numbers. The constructor should accept an integer argument and dynamically al

attashe74 [19]

Answer:

See explaination for the code

Explanation:

Here is the code

class NumberArray

{

private:

float *aptr; // Pointer to the array

int arraySize; // Holds the array size

float max,min,avg;

public:

NumberArray(int); // Constructor

~NumberArray(); // Destructor

int size() const // Returns the array size

{ return arraySize; }

void storeNumber(float num,int ele);

float retrieveNumber(int ele);

float getHighest();

float getLowest();

float getAverage();

};

//*******************************************************

// Constructor for IntArray class. Sets the size of the *

// array and allocates memory for it. *

//*******************************************************

NumberArray::NumberArray(int s)

{

arraySize = s;

aptr = new float [s];

for (int count = 0; count < arraySize; count++)

*(aptr + count) = 0;

}

//******************************************************

// Destructor for IntArray class. *

//******************************************************

NumberArray::~NumberArray()

{

if (arraySize > 0)

delete [] aptr;

}

void NumberArray::storeNumber(float num,int ele)

{

if(ele<arraySize)

*(aptr+ele)=num;

}

float NumberArray::retrieveNumber(int ele)

{

return *(aptr+ele);

}

float NumberArray::getHighest()

{

float high=*(aptr+0);

for(int i=1;i<arraySize;i++)

if(high<*(aptr+i))

high=*(aptr+i);

return high;

}

float NumberArray::getLowest()

{

float low=*(aptr+0);

for(int i=1;i<arraySize;i++)

if(low>*(aptr+i))

low=*(aptr+i);

return low;

}

float NumberArray:: getAverage()

{

float ag=0;

for(int i=1;i<arraySize;i++)

ag+=*(aptr+i);

ag=ag/arraySize;

return ag;

}

//Header file section

c++ 2.30 LAB: Phone number breakdown Given a long long integer representing a 10-digit phone number, output the area code, prefi

Nady [450]

Answer:

#include <iostream>

using namespace std;

int main()

{

//declare variable to store phone numbers,its area code, prefix and line number.

long phone_number;

int area_code, prefix,line_number;

cout<<"Enter 10-digit phone number:"<<endl;

//input 10-digit phone number

cin>>phone_number;

//logic to find area_code, prefix, and line_number.

area_code = phone_number/10000000;

prefix = (phone_number/10000)%1000;

line_number = phone_number%10000;

//output phone number in asked format.

cout<<area_code<<"-"<<prefix<<"-"<<line_number<<endl;

return 0;

}

Output:

Enter 10-digit phone number:

8005551212

800-555-1212

Explanation:

In the above program 10 digit phone number entered by user will be stored in the variable phone_number.

Then using this phone_number variable area_code, prefix, and line number are calculated using the following logic:

area_code = phone_number/10000000;

prefix = (phone_number/10000)%1000;

line_number = phone_number%10000;

Finally these area_code, prefix, and line_number are displayed with hyphen in between using cout statement.

A manufacturing company has several one-off legacy information systems that cannot be migrated to a newer OS due to software com

Digiron [165]

The resiliency technique which would provide the aforementioned capabilities is: D. Full backups.

An operating system (OS) can be defined as a system software which is pre-installed on a computing device, so as to manage or control software application, computer hardware and user processes.

In this scenario, a manufacturing company cannot migrate its several one-off legacy information systems (IS) to a newer operating system (OS), due to software compatibility issues.

Resiliency can be defined as a measure of the ability of a network, server, storage system, computing system or data center, to recover quickly and continue operating when it experience adverse conditions such as:

Power failure.

Equipment failure.

Data loss.

In Computers and Technology, there are four (4) main resiliency technique and these include:

I. Redundancy.

II. RAID 1+5.

III. Virtual machines.

IV. Full backups.

Full backup is a resiliency technique which create backups of the systems for recovery and it allows operating system (OS) patches to be installed on computer systems.
