HELP PLEASE. DYnamic variable

You'll need a pointer for this. Allocate the memory for it during the calculation, and then delete it when you have no further use of the data.

where ? where in the class that was my question. where do i declare the pointer, in public, in private. no one knows ?

[TwilightSpectre]

Not in the class. I think they want you to manually allocate the variable within main, and then do things, and then delete it again, like this:

//...

class Area {
    // ...
};

int main() {
    Area *a = new Area;

    // do stuff with a

    delete a;
    return 0;
}

I understand that what he is trying to do is make us access the private variable through the dynamic variable. correct ?

No.
Dynamic or not, you won't be able to access a private variable.

It looks like you are required to write Getters and Setters maybe?

Ahh.. we haven't learned those though. I can write a public function and access the variables and compute one half of the area like he asked us to that would not be an issue, but... i wonder what would be the use of the dynamic variable, why did he ask us to declare one.

again I suck at pointers and dynamic variables so my understanding to their use is limited.

[mutexe]

looks like you will need:

void SetArea(float area);
void Setunits(string units);
float CalculateHalfArea(void);

OR, just

float CalculateHalfArea(float area, string units);

as your public interface (depends on if you want to save your units and area inside your object, which is looks like you do).

[Bleedz129]

okay so public functions, got ya.. what about the dynamic what is the use of it...

[mutexe]

NT3 gave you a could example above.

as to what use it is using a dynamic variable in this context.. none whatsoever.
