Better to have tried to help and found out it was likely to be a spam bot than ignore someone who really is needing help.
Though just dumping what looks like a school assignment and expecting us to do the work gratis certainly doesn't encourage me to "bump a hump" writing even simple code. If'n the OP makes SOME effort by showing they tried to write code makes helping easier to justify taking the time.
True. As far as "doing the work"; if they ask a concise question about a very specific issue, then it's easy enough to just show a bare-minimum example. In general, it's a case-by-case basis. For this topic, asking "how do I write exp(j omega t) in C++" is focused and doesn't sound like something like homework (at least, not a whole assignment), so I'm more likely to throw them a bone.
