Answer 1

Solve
Output:

1 20 1
Explain:
In printf exist assignment to x, it execute first. So, at printf value of x is 20.
Since 20≠15, we have true value and as integer this expression have value 1
Since x=20, second output – is output x, so, we have 20
Since 20<30, we have true value and as integer this expression have value 1
Since string line start from \n, this line prints from new line
