Source Code

Consider the following program

#include <iostream.h>
#include <conio.h>


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.
