     Logical Bug in C++. C++ contradicts its own errors by saying that p is a constant, and in the next line says that p is not a constant.

 
				Consider the following program


#include
#include


void main()
{
int n;
cin>>n;
const int p = n;
p++;// C++ gives error that p is a const
int a[p]; // C++ gives error that p is not a const
}
Now how can c++ give an error for p being a constant in first commented line and also an error for p not being a constant in the second commented line.....logical huh? And the program compiled perfectly till the line
const int p=n;
(This line is accepted).

Anyone with a way out, plz write a message. And if u feel that this discovery is worth a credit, plz vote.
