If you want unique random numbers you'll need to either remove duplicates after generation as @Timothy Kanski suggested or use something like std::find to check if the container already contains the generated number during the loop; or use a different container such as std::set to avoid equivalent values occurring. Harvard mathematician Oliver Knill told Live Science his favorite number is the Apry's constant (zeta(3)), "because there is still some mystery associated with it."
