Need some help using class in C++

I'm having some difficulty using class in arduino code.

I'm experienced with classes in Processing or Java but haven't used C++ for many times. I just want to define a class and use it in my arduino code. Here is my code. It won't compile :error: expected initializer before 'potato'. Can someone point out what I did wrong and the right way to do it? Thanks.

class stuff
{
public:
int name;

stuff(int n)
{
name=n;
}

void run()
{
// do something
}

}

stuff potato=stuff(2);

void setup()
{
}

void loop()
{
}

Realized my mistake was missing a ";" on the last line of class definition. Ah.
