What is the execution sequence for the code (x = i++ + ++i) ?

[robertcullen]

main()
{
int i=1;
int x;
x=i++ + ++i;
printf("%d",x);
}

Strange how this question has arisen so many times recently. Look here and here and here.

I want to know how compiler compile this code?
In which sequence it is going to execute.
firstly "i++" or "++i".
Its Associativity?

This is a trick question; nobody can answer it. The explanation is in those links I gave you in my first reply.

I'm curious why you're asking about this.

I suggest it is clever question set by a tutor as an assignment,
to test the students understanding of compiler logic.

So an explanation of why it is impossible to answer is what the tutor is looking for.
