output is k = 5 because:
  1. Compiler told me.
  2. This is how comma operator works, namely: "[comma] is a binary operator that evaluates its first operand and discards the result, and then evaluates the second operand and returns this value (and type)" (see Comma operator at Wikipedia[^]).
    3.  
    Hence evaluation steps are:
    1. i = 4 (discarded)
    2. j = 5 (returned)
    3. k = 5 (k gets the returned value of the comma operator)
