Date: Mon, 21 Feb 2000 03:25:49 +0100 Message-ID: MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit X-Priority: 3 (Normal) X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook IMO, Build 9.0.2416 (9.0.2910.0) Importance: Normal X-MimeOLE: Produced By Microsoft MimeOLE V5.00.2314.1300 I tried to get random numbers in a C++ programm with the two functions srand(number) // to initialize x=rand() // to get a number but the compiler gives me a warning that says 'implicit declaration of function 'srand()'' and the same for 'rand()'. Is there another way to get random numers in C++? I'm asking because under linux the compiler will stop com- piling. It is a error for the g++-compiler that comes with the debian potato. After I installed egcs, I got a warning, but the compiling finished. Under Cygwin its also a warning and no error.
