nadya68 [22]

Answer:

The answer is "Option A".

Explanation:

Please find the complete program in the attached file.

The given program includes a super-class Bike having a private integer numWheels parameter. The class EBike inherits the class Bike, EBike comprises one parameter function Object() which utilizes its variable number of the private integer Battery level of the battery parameter and the wrong choice can be defined as follows:

In choice B, it is wrong since there is no constructor with a single argument in the Bike class.

In choice C, it is wrong since there no need to call the base class constructor with the super keyword.

In choice, D is wrong because there no need to create a constructor of the base class.

In choice, E is wrong because it does not require the second EBike constructor parameter.

//define header file

#include <iostream>

// using namespace

using namespace std;

class Accumulator

{

//set private access modifier

private:

}

//define integer type function

int getSum()

{

//return the value of sum

return sum;

}

//define void type function

void add (int value)

{

//variable sum is increased by the argument value

sum += value;

}

  • Define a integer data type function 'getSum()' that return the value of the variable sum.
  • Finally, define a void type function 'add()' and pass the integer data type argument 'value' in its parameter in which the variable sum is increased by the argument value .
