how to use class variable in class ?

Question

I want to use variable in class

class Path{
public:
float get_x(){
int x=0;
for(int i=0;i<ARRAYSIZE(Paths);i++){
	if(Paths[i].r){
		return Paths[i].id;
	}
}
}
}
Path Paths[30];

but there will be error right? I can not use Paths in class

It is better to make this a templated static member. The array can then be passed in as a parameter.

class path
{
public:
	template <unsigned int N>
	static int do_stuff(path(&paths)[N])
	{
		return paths[0].id;
	}
private:
	int r;
	int id;
};

int wmain()
{
	path paths[20];

	path::do_stuff(paths);
	return 0;
}

It would be even better to not use C style arrays and instead use std::array or std::vector.
