What about the people explaining the answer above as '12'saying processing will start from left in cout and write in printf ??

For such type of questions, the best method is to draw a parse tree according to precedence and evaluate the tree. This is how it is evaluated at compiler level.

Manish is right. This would start from the left. In cout also processing starts from left.

Yes it is correct that if we apply rules for postfix and prefix operators, the answer should be 12,5 but it is showing 10,5. So please explain this.
