Answer:
dataFile << salary;
Explanation:
To write salary to a file (payroll.dat) using ofstream, you make use of the following instruction:
<em>ofstream dataFile;
</em>
<em>myfile.open ("payroll.dat");
</em>
<em>myfile <<salary;
</em>
<em>myfile.close();</em>
<em />
This line creates an instance of ofstream
<em>ofstream dataFile;
</em>
This line opens the file payroll.dat
<em>myfile.open ("payroll.dat");
</em>
This is where the exact instruction in the question is done. This writes the value of salary to payroll.dat
<em>myfile <<salary;
</em>
This closes the opened file
<em>myfile.close();</em>
<em />
<em />
The following cose will be used to copy assignment operator for CarCounter
<u>Explanation:</u>
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;
}
A. Resize
By dragging the border of a field or record, you are either enlarging it or compressing it. Choices "b" and "d" are only half correct, as there is always the possibility of making it smaller. Hope this helps!
Answer:
2. A data modelling project using a packaged data model REQUIRES A GREATER SKILL than a project not using a packaged data model.
Explanation:
1a. Review of universal models:
A data model is an abstract model that organizes elements of data and standardizes how they relate to one another and to the properties of real world entities. It has become the standard approach used towards designing databases.
A universal data model is a template data model that can be reused as a starting point or a building block to jump-start development of a data modelling project, industry specific model, logical data models.
1b. Discuss how these are being used more widely today.
*Universal data models helps professional reduce development time, improve consistency and standardization while achieving high quality models.
*Higher quality: just as architects consider blue prints before constructing a building, one should also consider data before building an app. A data model helps define the problem, enabling one to consider different approaches and choose best ones.
*By properly modelling and organization's data, the database designer can eliminate data redundancies (needless repetitions) which are a key source for inaccurate information and ineffective systems.
2. Greater and advanced skills are adequate and required when data modelling project is done using packaged data model while fewer skills are required when data modelling is done without packaged data model.
Answer:
Interference.
Explanation:
As the user is communicating with their friend through the mobile, most of their interaction is interrupted by the noise of an airplane flying at low hight. Instantly afterward, the user's mobile phone rang, disrupting the communication once more.
So, according to the following scenario both of those are examples of interference.
