If we write int a=42 and then write a do...while loop,we write cout..... and then a++ why doesn't it change the value of a

Question

when the condition in while is false??

Answer 1

Output is based on FIFO(First in First Out)
That is, the query you write first, will be executed first, and then it will end followed by execution of the next query.
Sive you wrote cout before a++;, it will be executed first.
