o the state of v after expr-cond is definitely assigned or “definitely assigned after true expression”.

· The definite assignment state of v before expr-false is definitely assigned if and only if one of the following holds:

o expr-cond is a constant expression with the value true

· the state of v after expr-cond is definitely assigned or “definitely assigned after false expression”.
