Concept of Pointer Parameter

Pointers are the special variable that stores the variable address, instead of storing the variable value. Pointer is a powerful feature of a programming language. A pointer is mostly used to save memory space and improve execution time.

Question

Convert the given program using the derived data type "C++union", for which you can generate
the same output.
#include <iostream>
using namespace std;
struct child
{
double age;
char grade;
};
int main()
{
child baby = {3.2,'M'};
cout « "Age = " « baby.age « endl;
if (baby.grade == 'F')
cout « "Grade = Floor" << endl;
else
cout <« "Grade = Not Known" « endl;
return 0;
}
