What will be the output of the following program?

int main() { union { int i; int j; void f() { printf("i=%d, j=%d\n", i, j); } }; i = 3; j = i+++ ++i; f(); return 0; }

ERROR

i+++ at line 20 is not executable.

pardon me if I am wrong.

i = 5, j = 8

This statement,: j = i+++ ++, i is actually

j = i++ + ++i;

i = 3 at first, then starting from left we look at i++, so the expression takes the values as 3 because i++ is a post-increment and afterwards increments i to 4. Then it looks at the other part of the expression which is ++i so for this it does a pre-increment and i becomes 5 and then 3 + 5 is added together and assigned to j.
