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.
