Structure of the vector into why there will be a problem?-CodePudding

Is the following code:
Out of it when I use buf is new push_back a Node * there will be a problem, and I'm buf is directly in the global area declare there is no problem:

 # include 
# include 
# include 
# include 
# include 
# include 
# include 
# include 
# include 
Using namespace STD. 
The class Node {
Public: 
VectorVector Cost; 
Vector The count. 
};//buf [1000]. 

Int main () {
Freopen (" F://Temp/input. TXT ", "r", stdin); 
Int n, m; 
Cin & gt;> N & gt;> m; 
Node * buf=new Node [n].//so below (1) other complains 
For (int I=0; I & lt; N - 1; + + I) {//there are n - 1 road 
Int s, t, c; 
Cin & gt;> S & gt;> T & gt;> C; 
Buf [s]. Cost. The push_back (c); 
Void * p; 
Node Node * TMP=new (p); 
Buf [s]. Next. Push_back (TMP);//(1) 
} 
return 0; 
}

There is the following error: under VS2013

Ask what the problem is, my classmates and I couldn't think what the problem with the accident at the mirror for a long time,
