Defining NULL for an array of pointers in C++ -

i wrote class in c++. in wrote:

class node{ private: node*m[200]=null; }; 

(this part of class) receive errors. should defining array of pointers, null ?

to make 200 pointers null, write:

class node {     node *m[200] = {}; }; 

this valid in c++11 , later.
