[Dev-C++] symbol unsure

I came across some code references online, and trying to figure out what =
does=20
' +=3D ' stand for.

e.g.  firstnamelength +=3D 10;

=3F=3F=3F=3F

Hello,=20

As we can see the compiler complains about the class
definition in the *.cpp file.

>  \myFolder\myClass.cpp In constructor
> `myClass<Type>::myClass(const Type&)':
>=20
> 7 \myFolder\myClass.cpp syntax error before `;'
> token=20
> \myFolder\Makefile.win [Build Error]  [myClass.o]
> Error 1=20

And, the complaint is about the way you have created a
new myClass object. Firtsly, you have declared a
protected member object of type Type in the class
declaration and not a pointer to an object of type
Type. So I guess the declaration code should be
changed to:

Type* count; // Declare count as a pointer.

Next, even after making such a correction, the way you
should go about initialising this object is:

count =3D new Type(item);

and not as:

count =3D new Type item;

Even here, the class of type Type should have a
logically correct copy constructor.

> Lastly, here is my myClass.cpp code:

> myClass<Type>::myClass(const Type &item) //default

> }

Hope this helps,
Siva Chandra
