Error complaining about redeclaration of parameter

[Flurite]

Hello,

I am receiving a strange error,

declaration of 'class_friendOverload setClass' shadows a pararmeter

in this member function definition:

class_friendOverload& class_friendOverload::operator=(class_friendOverload& setClass)
{
    class_friendOverload::class_friendOverload(setClass);
    return *this;
}

If you would like to see the function class_friendOverload::class_friendOverload(const class_friendOverload&), which is my copy constructor, this is what it looks like:

class_friendOverload::class_friendOverload(const class_friendOverload& setClass)
{
    this->m_value1 = setClass.m_value1;
    for (int i = 0; i < 5; ++i)
    {
        this->m_array1[i] = setClass.m_array1[i];
    }
}

¿which compiler are you using?
class_friendOverload::class_friendOverload(setClass); is invalid and makes no sense.

[vlad from moscow]

class_friendOverload& class_friendOverload::operator=(class_friendOverload& setClass)
{
class_friendOverload::class_friendOverload(setClass);
return *this;
}

Though your code has no any sense nevertheless it looks like a compiler bug. In interprets the bolded statement as definition of variable setClass.

@ne555 & vlad from moscow,

I am trying to call the copy constructor. So it is not possible to call any type of constructor, and instead I should have it call something like a Clone() method?

[vlad from moscow]

Of course you may try to call the copy constructor, but there is no any sense. Your object is already constructed. In realty in this statement you create a temporary unnamed object that will be destroyed after semicolon.:)

Consider

class_friendOverload obj = class_friendOverload(setClass);


and now remove the left part of the statement. What will you get?

@vlad from moscow,

Nothing/void?

[vlad from moscow]

Yes.

class_friendOverload(setClass);

an temporary unnamed object is created and destroyed in the same statement after semicolon.
