Talk:Pick random element
The task should clarify if the elements should be taken at random with equal probability (that is, discrete uniform distribution, insofar as the underlying pseudorandom generator allows this). It seems obvious, but it's not stated, and if so, there are wrong entries in the page.
For instance, the C program does not yield a uniform distribution. The correct solution is explained in the accepted answer to this Stack Overflow question: How to generate a random number from within a range.
The same bad C code is reused in the Loops/Break task, and I fear many could use the Rosetta Code program as is without suspecting a problem.
