S = 12 + 22 + 32 + 42 . . . + n2
Answer:
- Copy constructor is used for creating the second object as defined in the above program.
- In main() function, two objects are created using copy constructor. The program displays the Output: as per the series: S = 12 + 22 + 32 + 42 . . . + n2
- The above figure shows the actual execution of series and how it works using lnline member function and copy constructor.
#include<iostream>
using namespace std;
class Series
{
int num, i, sum;
public:
Series(int x)
{
num=x;
sum=0;
}
Series (Series &x)
{
num=x.num;
sum=0;
}
void calculate();
void display();
};
inline void Series::calculate()
{
for(i=1; i<=num; i++)
{
sum=sum+i*i;
}
}
inline void Series::display()
{
cout<<"\n Value of the Series : "<<sum;
}
int main()
{
int x;
cout<<"\n Enter Value : ";
cin>>x;
Series se1(x);
se1.calculate();
se1.display();
Series se2(se1);
se2.calculate();
se2.calculate();
return 0;
}
Output:
