Is this legal C++

This works in MSVC++ but not in Borland C++ Builder:

Code:

---


//Can contain a number, string or something
class DataType
{
public:

  DataType( double num);

  //Other constructors

private:

  //Contains type and data
};


DataType foo( )
{
  double bar = 1;

  return bar;
}

---

Borland wants me to write

return DataType(bar);

According to the ANSI/ISO standard, is this required?

Code:

---

DataType foo( )
{
  double bar = 1;

  return bar;
}

---

your return type here is DataType, but you're returning a double.

lol.... er, I'm sorry

Reading code back to yourself sometimes does help find errors...

Code:

---

Define function foo - no arguments with return type DataType
Declare variable bar as double and set to 0
Return from foo with bar

---

I dunno, I've gotten used to reading my code, so the type mismatch sticks out to me

One day,I did the same thing...

That is a reg. programmer problem... it is ok ... :D

I know perfectly well what the problem is.

But because DataType has a constructor that takes a double, MSVC++ does the conversion automatically. Borland does not.

You can write:
double a = 1.5;
DataType d = a;
There's no more ambiguity in writing
return a;

Now you got it right...
:o ;)
