[Discuss-gnuradio] GRC newbie questions

[Barry Duggan]

1) Are the terms 'vector' and 'array' synonymous?
2) If the input to a block is an array of X bytes, and I produce an 
output array of Y bytes, is that still considered a sync_block, i.e. one 
array in, one array out?
3) For Python, what is the advantage of building an OOT block vs. using 
a Misc. Python Block in a single flow graph?
4) There is only a brief mention of using C in place of C++. Is there 
any problem in doing so?

Thanks
