this pointer

[salmanmanekia]

Below is the code and the error ,i am not able to get the reason for it,this is not in anyway necessary but it looks good and effiecient and above all now i have a oppurtunity to see how much can it misbehave so i am using it

View

void height(int heightValue)
{
	myScene->height(heightValue);
}

void height(int heightValue)
{
	myScene->height(heightValue);
}

To copy to clipboard, switch view to plain text mode 

Scene

private:
    int heightValue;
 
void height(int heightValue)
{
	this.heightValue = heightValue;
}

private:
    int heightValue;

void height(int heightValue)
{
	this.heightValue = heightValue;
}

To copy to clipboard, switch view to plain text mode

Where is the error ? I cant see it

By the way.. this is a pointer.. so you cant use dot operator with it.

you have to use something like this->

Where is the error? this->heightValue = heightValue is perfectly acceptable code and used to define the scope of the variable (However, personally I would use m_heightValue rather than this->heightValue)

and, this is a pointer, so you need to use -> not .

As previously pointed out:

this is a pointer, and thus you have to dereference it with -> or (*) before using
it in the manner in which you're trying to do. Also, it's best to have private member variables
(m_) for classes with accessors and mutators so that you can maintain strict controls on who is
able to modify them. It might not be an issue for a simple test application, but it's good practice
to learn for coding larger projects with several people
Also, if you're looking for bad usages of this, some people feel that usage of this in the constructor is bad practice, as you're referencing an object that isn't fully formed.
