I came across some code references online, and trying to figure out what =

' +=3D ' stand for.

e.g.  firstnamelength +=3D 10;

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.

Hope this helps,

Just wondering does anyone know what this syntax would be used for:

Example:

start =3D  "\002";
=66inish =3D  "\026";

I know that it might be a repeat delimiter (\) but now sure how it is used.=
 =
Tried looking online for some help but very vague references.=20

Thanks.

This is the syntax to write ASCII characters directy inside a string.
E.g. \097 should be equal to 'a'

But how can you use the = operator to Strings in Cpp?

[Per W. <pw...@ia...>]

Octal specification works fine, but more often hexadecimal is more
intuitive, i.e. "\x40" for '@'.

What was the question about the = operator?

using c strings, = assigns the pointer to a string, to the actual string
contents. Using the std::string data type on the lefthand side, = assigns
a new c string to the c++ object, i.e. calls the operator= method for the
std::string class object.

It means
firstnamelength = firstnamelength + 10;
You can use it with +,-,*,/ and %. See one more example
below:
"firstnamelength /= 10;" ==> "firstnamelength = firstnamelength / 10;"

You also missed bit and shift operations :)
&=
|=
^=
<<=
>>=
