Question

void sum()

sum=a+b;
}
};
void item :: getdata()

}
int main()

item x;
cout<<"\nobject x "<<"\n";
x.getdata();
void sum();
cout<<sum;

Answer 1

I finally got it.......

#include <iostream>
using namespace std;

class xyz
{
int a,b,sum;
public:
xyz()
{
cin>>a>>b;
sum=a+b;
}
void disp();
};
void xyz::disp()
{
cout<<"sum="<<sum;
}

int main()
{
xyz i;
i.disp();
return 0;
}

Thanks....

Answer 3

Can you post the error message?

You cannot acces the member function sum by "void sum()"

The member function sum should have a return value:

int sum(){
return a+b;
}

int sum = x.sum();
cout<<sum;

Answer 4

you variable sum and method sum bot have same identifier.
change method sum to getsum() and it will work fine
