Answer: Option D -- Sorting an already sorted array of size n with quicksort takes O(n log n) time.
Explanation:
Sorting an already sorted array of size n with quicksort takes O(n log n) time is true about sorting functions while other options are wrong.
Answer:
Following are the code to this question:
CarCounter::~CarCounter()//Defining destructor CarCounter
{
cout << "Destroying CarCounter\n";//print message Destroying CarCounter
}
Explanation:
Following are the full program to this question:
#include <iostream>//Defining header file
using namespace std;
class CarCounter //Defining class CarCounter
{
public:
CarCounter();//Defining constructor CarCounter
~CarCounter();//Defining destructor CarCounter
private:
int carCount;//Defining integer variable carCount
};
CarCounter::CarCounter()//declaring constructor
{
carCount = 0;//assign value in carCount variable
return;//using return keyword
}
CarCounter::~CarCounter()//Defining destructor CarCounter
{
cout << "Destroying CarCounter\n";//print message Destroying CarCounter
}
int main() //Defining main method
{
CarCounter* parkingLot = new CarCounter();//Defining class object parkingLot
delete parkingLot;//
return 0;
}
- In the given C++ language code, a class "CarCounter" is defined, and inside the class, a "constructor, Destructors, and an integer variable" is defined.
- Outside the class, the scope resolution operator is used to define the constructor and assign value "0" in the integer variable.
- In the above-given code, the scope resolution operator, to define destructor and inside this cout function is used, which prints a message.
- In the main method, the class object is created, which automatically calls its class constructor and destructors.
Answer:Buying Later
Explanation: Buying later would be the better choice because not only will you feel reawrded for working hard to get what you want but you also will not have to o throught the hassle of getting a loan. It may also be cheeper becuae many loans charge interest.
In Python, tuples are indeed a data structure that also stores an ordered sequence of unchanging values, and following are the Python program to the given question:
Program Explanation:
- Defining a method "add_tuples" that takes three variables "firstTuple, secondTuple, thirdTuple" into the parameter.
- After accepting the parameter value a return keyword is used that adds a <em><u>single tuple with two values</u></em> and returns its value into the form of (x,y).
- Outside the method, two print method is declared that calls the above method by passing value into its parameters.
Program:
def add_tuples(firstTuple, secondTuple, thirdTuple):#defining a method add_tuples that takes three variable in parameters
return firstTuple[0]+secondTuple[0]+thirdTuple[0],firstTuple[1]+secondTuple[1]+thirdTuple[1] #using return keyword to add value
print(add_tuples((1,4), (8,3), (14,0)))#defining print method that calls add_tuples method takes value in parameters
print(add_tuples((3,2), (11,1), (-2,6)))#defining print method that calls add_tuples method takes value in parameters
Output:
