Answer:
C. Inaccurate and misleading data can be more easily disseminated to scientific researchers.
Explanation:
The above one is certainly the correct option. We know these kinds of the database as an open database, and these are available for all on the internet. The best example is the World Bank database, Census.org is also a good example. All these databases are a huge collection of data sets with meaningful data. The inaccurate and misleading data is never thought to be spread among the scientific researchers easily as it is not good for research, and requires a huge level of data cleaning. Hence, C. is the correct option here as it is not an advantage.
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.
