Alexus [3.1K]

Answer:

I am writing partial code in c++ to calculate weighted average. The weighted average should be calculated based on multiplying the test score and its respective weight and finally add all the test score.

Explanation:

int arrtestscore[100];

int arrweight[100];

int n;

double weightedavg;

cout<<”Enter the number of test score for which weighted average needs to be calculated”;

cin>>n;

for(int x = 0; x <n;x++)

{

 cout<<”Enter test score :” + (x+1) ;

 cin>>arrtestscore[x];

 count<<”Enter the respective weight:”;

 cin>>arrweight[x];

}

for (int i=0; i<n;i++)

{

 weightedavg = weightedavg + (arrtestscore[i] * arrweight[i])

}

cout<<”weighted average = “ <<weightedavg;

Write a copy assignment operator for CarCounter that assigns objToCopy.carCount to the new objects's carCount, then returns *thi

Olin [163]

The following cose will be used to copy assignment operator for CarCounter

Explanation:

Complete Program:

#include <iostream>

using namespace std;

class CarCounter

{

public:

CarCounter();

CarCounter& operator=(const CarCounter& objToCopy);

void SetCarCount(const int setVal)

{

carCount = setVal;

}

int GetCarCount() const

{

return carCount;

}

private:

int carCount;

};

CarCounter::CarCounter()

{

carCount = 0;

return;

}

// FIXME write copy assignment operator

/* Your solution goes here */

CarCounter& CarCounter::operator=(const CarCounter& objToCopy)

{

if(this != &objToCopy)

carCount = objToCopy.carCount;

return *this;

}

int main()

{

CarCounter frontParkingLot;

CarCounter backParkingLot;

frontParkingLot.SetCarCount(12);

backParkingLot = frontParkingLot;

cout << "Cars counted: " << backParkingLot.GetCarCount();

cout << endl << endl;

system("pause");

return 0;

Consider a disk that rotates at 3600 rpm. The seek time to move the head between adjacent tracks is 2 ms. There are 32 sectors p

jasenka [17]

Answer:

19.71 ms

Explanation:

The disk rotates at 3600 rpm, hence the time for one revolution = 60 / 3600 rpm = 16.67 ms.

Hence time to read or write on a sector = time for one revolution / number of sectors per track = 16.67 ms / 32 sectors = 0.52 ms

Head movement time from track 8 to track 9 = seek time = 2 ms

rotation time to head up sector 1 on track 8 to sector 1 on track 9 = 16.67 * 31/32 = 16.15 ms

The total time = sector read time +head movement time + rotational delay + sector write time = 0.52 ms + 2 ms + 16.15 ms + 0.52 ms = 19.19 ms
