I'm populating a 2d array and wondering if it is valid to leave one
dimension with blank brackets while i assign a value to the other

thinking of doing:
zSet[i][ ] = lineZ[i+ (i-2)+11];
zSet[ ][i] = lineZ[i+ (i-1)+11];
No, you can't do that, you have to assign to each element
individually. All you can do is "populate" a complete row
in one go if you want to initialize it from a row of another
array of at least the same size and the same type by using
memcpy() but that's it. There isn't any implicit looping over
arrays of any dimensions in C.
Oh ok, thanks.
