I have never been able to understand the C language question. I only have a few lines of code and the answer is there.

Question 1: ?pA?+?10?=?（unsigned?long）PA?+?10?*?sizeof（*PA）=?0x10000000?+?10?*?16

Question 2: (char*)?pA?+?10?=?(unsigned?long)PA?+?10?*?sizeof(char)?=?0x10000000?+?10?*?1

Question 3:?(int*)?pA?+?10?=?(unsigned?long)PA?+?10?*?sizeof(int)=?0x10000000?+?10?* ?4
