C++ TR1 Random Number Gen

[4oL1hbRD]

Anyone know of any good documentation on the <random> header of TR1.
I can hardly find anything.

I did find the following example for picking a random# between 1 and 10
at http://www.johndcook.com/cpp_TR1_random.html#start

However, what is "eng". Visual Studio 10 does not recognize it.

And it give me a conversion error. I tried static_cast but that wouldn't work
either.

Anyway, how do I store this random# as an int. Thanks.

    std::tr1::uniform_int<int> unif(1, 10);
    int x = unif(eng);

eng is an instance of one of the engines mentioned earlier.

This might help. I'm not sure how different the TR1 implementation is from the original Boost though.

Thanks. I'll try the boost libraries sometime.

For the TR1,

So "eng" is the engine. So let's say I want linear_congruential.

int x = unif(linear_congruential)

That does not work - name not recognized.

Do I need another header in additon to <random>? If so, what?

"#include linear_congruential" does not work. Am I missing files?
