#why doesn't my rng generator work ?

What doesnt work?
the uninitialized value should be a garbage value and random but i keep getting 0 which is even and always that instead of a random value

I think if you want something random, you should rather choose ways that are reasonable to the programme itself.

Maybe the value in that memory location is zero or your compiler auto sets it to zero. Normally thats UB and you should use a different method
naive stratus
this is undefined behavior. the compiler simply can do as it please. you cannot relay on some indeterminate value to be random
bitter tide
o hmm i thought uninitialized variables are always random
patent lake
in your word, it should be unexpective rather than unpredictable
patent lake
and yes, maybe it seems to be random to YOUR programme, but it will cause more problems than what you would ever want

(i mean you could just take your CPU temperature as a part of seed calculating formula, that is, if you really want to do something with RNG

Oo right

undefined behavior means the standard didn't associate any behavior for something. in practice this leaves things for the implementation. what actually may happen can vary. the compiler can insert some value there, can generate some code to load whatever in the stack at one point or crash the whole thing down. you cannot relay on it and shouldn't do so

ah i see
patent lake
that's true. you cannot rely on it
