There is no variability concerning ISO C++ features these days.


A question: With .NET facilities, when one performs an invalid operation 
like accessing an array out of its bounds an exception is thrown and the 
program terminates indicating what was the problem.


This is the kind of run-time safety Ada provides or is there something else?


int main()
{
     using namespace System;

     array<int> ^someArray= {1,2,3,4,5,6,7,8,9,0};

     someArray[10]= 7;
}


C:\c>temp

Unhandled Exception: System.IndexOutOfRangeException: Index was outside 
the bounds of the array.
    at main()

C:\c>
