C++ gurus - I need a bit of help!

How do I retrieve the time from the computer's clock? What header file do I need?

my compiler says that std::time() takes in a double to a pointer - so this clearly not what i want

 

[KarsinTheHutt]

Anyone know?

sorry, no clue. i'm still fooling around with BASIC

sh!t



My program's srand() can't seed very randomly unless i can retrieve the time and use that as a seed.

This is what I use on a unix based system...

#include <time.h>

time_t myTime;
myTime = time(NULL);
cout << ctime(&amp;myTime) << endl;

Have you tried this:

srand( (unsigned) time(NULL) );

Even though the time() function doesn't return a value that's type &quot;unsigned&quot;, the return's still the current time in a weird form (for VC++, it's stored in an &quot;long&quot, so you can still seed the random number generator with it.

Hope that helps.

btw, this is from the .H files in VC++, so YMMV.

(other related files in the /go directory)

EXE of program... have a little fun gambling

EDIT: don't forget the .txt file needed to run the program
