Constructor in c++ : Sum of all multipliers

write a c++ program which contains a constructor to make sum of all multipliers of 7 or 9 between 1 and 100.



#include <iostream>
using namespace std;
class multipliers
{
public:
int sum=0,number;
multipliers();
~multipliers();
void getsum();
};
multipliers::multipliers()
{
}
multipliers::~multipliers()
{
}
void multipliers::getsum()
{
cout<<"All  multipliers  of 7 or 9 between 1 and 100 is : ";
for(number=1;number<=100;number++)
{
if ((number%7==0)||(number%9==0))
{
cout<<number<<"  ";
sum+=number;
}
}
cout<<"\n\n The sum of all multipliers of 7 or 9 between 1 and 100 is : "<<sum<<endl;
}
int main()
{
multipliers m;
m.getsum();

}
