get random numbers in C++ : implicit declaration ????

[Ajit George]

Did you include stdlib.h?  On linux the man pages state which header file
prototypes the functions described.

Subject:	get random numbers  in C++ : implicit declaration ????



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.

PS.: I included the iostream.h and the time.h
