how to solve iiegeal structure opearion error in binary opeartor overloading?

#include<iostream.h>
#include<conio.h>
class sum
{
    int a,b,ans;
public:
void  geta()
{
  cin>>a;
  return a;
}
void getb()
{
    cin>>b;
 
 
}
void operator+()
 
{
    ans=a+b;
}
void disp()
{
    cout<<ans;
}
};
void main()
{
  sum s,s1,s2;
  int a,b;
  s1.geta();
  s2.getb();
  s=b+a;
  s.disp();
}

The variable s is an object of the class sum:

s=b+a;
 

There is no method in class sum on how to assign an int (a+b) to a sum object. That is, you need a sum::operator(int) method.

That said, what are you trying to do? I am having trouble following your logic in main().
