Expression and evaluation order

    I am bit confused with evaluation order in expressions.Say for example in the following expression

    i + j + k++

    is subexpression k++ before any of the other operators.My understanding goes like this

    1) As ++ has higher precedence then +,(k++) is evaluated first
    2) then arithmetic + operators is evaluated from left to right

    So is my understanding correct?

    So can it be said tht given an expression all the unary operators are evaluated before any of the binary operators.

    Yes your understanding is absolutely correct and the evaluation is done based on preference.

    By the way Neha, welcome to the forum
