Error message showing type mismatch for 
(a ? b : c)
is printed below:
Error: incompatible types for ((b) ? (c)): 'B' and 'C'

Wrong '?' position.

It shoud be ... ((a) ? (b) : (c)): 'B' and 'C'

> It should be ... ((a) ? (b) : (c)): 'B' and 'C'

Nope, it should be:

> ((b) : (c)): 'B' and 'C'

Otherwise you can't determine what position 'B' and 'C' are in because the
ternary expression could be quite complex, e.g.:

> ((a) ? (a) : (b) ? (b) : (c)): 'int' and 'float'
