Are a++ and ++a the same?
Short answer. No. Postfix uses then adds; prefix adds then uses.
What is c after c = ++a when a is 6?
7.
Remember
| a++: use, then add |
| ++a: add, then use |
A plus plus, or plus plus a. Are they the same? No. Postfix uses five, then a becomes six. Prefix adds first, making seven. So b is five, c is seven. Postfix uses, then adds. Prefix adds, then uses.
