using srand()
Author
why do I get this error when I try to get a random nr?
error C2501: ''srand'' : missing storage-class or type specifiers
error C2373: ''srand'' : redefinition; different type modifiers
c:\vc98\include\stdlib.h(308) : see declaration of ''srand''
I use the following code in my program
#include
#include
#include
#include
#include
#include
#include
srand((unsigned)time(NULL)) ;
int block=rand()%7 ;
The only things that can be put outside of a function are declarations (including assignments to global variables).

I don''t get it now (the next day) my function alway returns the same number?!?
srand((unsigned)time(NULL)) ;
void RandomPiece()
{
while (!block)
{
block=rand()%7 ;
}
}
what could be wrong?!?
srand((unsigned)time(NULL)) ;
void RandomPiece()
{
while (!block)
{
block=rand()%7 ;
}
}

Are you sure your while() loop is ever run ?
In debug mode, variables are initialized by VC++ to a pattern of hexadecimal CCCC''s, so that, when you debug your program, if you see CC''s, you can scream "DUH, uninitialized variable !".

ah damn
stupid me
you''re right
when I enter the function block equals to a number so if block!=0 it doesn''t do that while loop
thanx for pointing me that out
