What is the value of last sample of a discrete sinewave

I have a simple question. If I compute N sample values of a single cycle of a discrete sinewave (whose initial phase is zero radians), will the value of the last sample be equal to zero?

No. Assuming the period of the signal is N samples since your indexing is zero based the $$Nth$$ sample will be indexed as $$N-1$$.
$$x[n] = A \sin \left( \frac{2\pi}{N}n \right)$$
Thus $$x[N]=0$$ and $$x[N-1] = x[-1] = -x[1]$$.
