Given ProblemSolution class. Use a pointer to object of "ProblemSolution" class to invoke the "CalculateSum" and "Print" methods

faltersainse [42]

Answer:

#include <iostream>

using namespace std;

class ProblemSolution {

private:

int num1, num2;

public:

ProblemSolution(int n1, int n2) {

num1 = n1;

num2 = n2;

}

int calculateSum() {

int sum = 0;

sum = num1 + num2;

return sum;

}

void printSum() {

// calculateSum will return sum value that will be printed here

cout <<"Sum = "<< calculateSum();

}

~ProblemSolution() {

cout << "\nDestructor is called " << endl;

};

int main() {

int a, b;

cout << "Enter a: ";

cin >> a;

cout << "Enter b: ";

cin >> b;

// Initiallizing object pointer of type ProblemSolution

ProblemSolution *objPtr = new ProblemSolution(a,b);

// printing Sum

objPtr->printSum();

// delete objPtr to relaease heap memory :important

delete objPtr;

return 0;

}

Explanation:

we will initialize a pointer "objPtr" and initallize the constructor by passing 2 values a and b followed by the keyword "new". the keyword "new" allocates memory in the heap. we can access class member functions using arrow "->". it is important to delete objPtr at the end of the program so that the heap memory can be freed to avoid memory leakage problems.

When is the following expression true? (2 points)

ipn [44]

Answer:

1) If and only if a and b have different values

Explanation:

Given

Expression: !(!a || b) || (!a && b)

Required

When is it true?

The expression is true when the values a and b are different and the proof is as follows.

(1) Assume that: a = true and b = false

!(!a || b) || (!a && b)

= !(!true || false) || (!true && false)

!true = false, so the expression becomes:

= !(false|| false) || (false && false)

In boolean, false|| false = false and false && false = false. So, we have:

= !(false) || (false)

!(false) = true, so, the expression becomes:

= true || (false)

Lastly, true || false = true

(2) Assume that: a = false and b = true

!(!a || b) || (!a && b)

= !(!false|| true) || (!false && true)

!false = true, so the expression becomes:

= !(true|| true) || (true && true)

In boolean, true|| true = true and true && true = true. So, we have:

= !(true) || (true)

!(true) = false, so, the expression becomes:

= false|| true

Lastly, false || true = true

<em>This expression is false if a and b have the same value</em>

How does an operating system manage peripheral devices?

azamat

Answer:

Device management controls peripheral devices by sending them commands in their proprietary machine language. The software routine that deals with each device is called a "driver," and the OS requires drivers for each of the peripherals attached to the computer.
