Thread: Conversion and Constructor Functions

Hi,

Code:

class X
{
    int i;
public:
    X(const int& val) : i(val)
    {}
    X operator+(const X&);
};

X X::operator+(const X &ob)
{
     return X(i + ob.i);
}

int main()
{
     X ob1(10), ob2;
    
     ob1 + 30; // this works like ob1 + X(30);
    
     30 + ob1; // NOT working in VC++. Any idea why???

     return 0;
}

Can any body throw any light as to why if
ob1 + 30 works why not 30 + ob1

thanks in advance,
