[Dev-C++] Ansi compatible?

[Anon <an...@pu...>]

Hey!
Can anyone please tell me if the following code is ANSI compatible? It =
compiles fine with DevC++ but throws up an error in Borland 5.0

#include <iostream.h>
#include <stdlib.h>

int main()
{
      int i=3D10;
      int arr[i]; //can it do accept Integer variable
      system("PAUSE");
      return 0;
}

My classmates say that this is a violation of ANSI standard.

#include <stdlib.h> 
 
[...]
 
  std::system("PAUSE");
 
std:: was not needed since you use the xxx.h notion for the C subset
header files. It would be needed if it was 
#include <cstdlib>

An array is not dynamic. It must me initalized using
a constant not a varible. Bad things can happen if the
value of 'i' changes while the program is running there
is nothing defined in the ANSI standard to remedy that
It comes down to your compiler. If it has code to correct
this problem then you have no problems. Otherwise expect a
BOOM!
