Yeah you're right they're not functions, I've corrected it, I haven't discussed the functions right now.

Hmm it's the way of learning. I've given an option to leave one question, and I'll be giving the solutions in the next posts with details. Neither to solve thes questions are obligatory to someone but for better understanding.

I know already which questions people would feel difficult to solve and if someone try they will become curious for the solutions.

We all have different ways of teaching, and as far as operator precedence is concern my teachers gave this task in class by not defining all most of the people did it by simple logic. (We were in first year)

I don't know but I defined all the things that are crucial for the task but the task is not that easy and I'll be providing solutions with details.

Thank you for leaving your comment. I liked you reviewed it.
