#include <iostream>
using namespace std;
class CarCounter {
public:
CarCounter();
CarCounter(const CarCounter& origCarCounter);
void SetCarCount(const int count) {
carCount = count;
}
int GetCarCount() const {
return carCount;
}
private:
int carCount;
};
CarCounter::CarCounter() {
carCount = 0;
return;
}
CarCounter::CarCounter(const CarCounter &p){
carCount = p.carCount;
}
void CountPrinter(CarCounter carCntr) {
cout << "Cars counted: " << carCntr.GetCarCount();
return;
}
int main() {
CarCounter parkingLot;
parkingLot.SetCarCount(5);
CountPrinter(parkingLot);
return 0;
}
Sample output:
Cars Counted: 5
How efficient well if we are transmitting 6bits and we need 10 to transmit the 6 bits that would be 6/10 = .6 = 60% efficient.
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The correct answer to this question is an online decision support system. Because the decision support systems process the data, evaluate and predict the decision, and helps the decision-makers, and offer real-time information immediately in making the decision in an organization. So the correct answer to this question is the decision supports system.
Why other options are not correct
Because the transaction processing system can only process the transaction and have not the capability to make the decision for the future. Office support processing system support office work, while the batch processing system process the task into the batch without user involvement. however, online executive processing does not make decisions and offer timely information to decision-makers in an organization.
Answer:
False
Explanation:
The private member of a class is not accessible by using the Dot notation ,however the private member are those which are not accessible inside the class they are accessible outside the class .The public member are accessible inside the class so they are accessible by using the dot operator .
<u>Following are the example is given below in C++ Language </u>
#include<iostream> // header file
using namespace std;
class Rectangle
{
private:
double r; // private member
public:
double area()
{ return 3.14*r*r;
}
};
int main()
{
Rectangle r1;// creating the object
r1.r = 3.5;
double t= r1.area(); // calling
cout<<" Area is:"<<t;
return 0;
}
Output:
compile time error is generated
<u>The correct program to access the private member of class is given below </u>
#include<iostream> // header file
using namespace std;
class Rectangle
{
private:
double r; // private member
public:
double area()
{
r1=r;
double t2=3.14*r2*r2;
return(t2); // return the value
}
};
int main()
{
Rectangle r1;// creating the object
r1.r = 1.5;
double t= r1.area(); // calling
cout<<" Area is:"<<t;
return 0;
}
Therefore the given statement is False
