Question

IN C++

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

Write a function:
   void Solution(int N1, int N2)

that accepts two integers N1 and N2. The function should instantiate “ProblemSolution” object with N1 and N2 values and call “CalculateSum” and “Print” method by creating a pointer to the object of “ProblemSolution”.

Input
   12 5

Output
   17
Assume that,

• N1, N2 and sum are integers within the range [-1,000,000,000 to 1,000,000,000].

Given Code to work with:

#include<iostream>
#include<cstdio>
#include<cstdlib>
using namespace std;

class ProblemSolution{
int N1,N2,result;
public:
ProblemSolution(int N1, int N2){
this->N1=N1;
this->N2=N2;
}
void CalculateSum();
void print();
};

void ProblemSolution :: CalculateSum(){
result=N1+N2;
}

void ProblemSolution :: print(){
cout<<result;
}

void solution(int N1, int N2){

   //write your code here

}

int main()
{
int N1, N2;
cin>>N1;
cin>>N2;
solution(N1,N2);
}

Answer 1

Program:

#include<iostream>
#include<cstdio>
#include<cstdlib>
using namespace std;

class ProblemSolution{
int N1,N2,result;
public:
ProblemSolution(int N1, int N2){
this->N1=N1;
this->N2=N2;
}
void CalculateSum();
void print();
};

void ProblemSolution :: CalculateSum(){
result=N1+N2;
}

void ProblemSolution :: print(){
cout<<result;
}

void solution(int N1, int N2)
{

ProblemSolution *ps=new ProblemSolution(N1,N2);
ps->CalculateSum();
ps->print();
}

int main()
{
int N1, N2;
cin>>N1;
cin>>N2;
solution(N1,N2);
}

Output:

12 5 17 ... Program finished with exit code o Press ENTER to exit console.
