所以推得pointer就是array,但C/C++並非如此,這個=是assignment的意思,也就是將array ia assign給pointer p,經過自動轉型後,將array ia第一個element的address assign給pointer p,這也是為什麼Pascal語系的assignment使用:=而非=,就是為了要跟數學區別,以免誤解。

In C, there is a strong relationship between pointers and arrays, strong enough that pointers and arrays should be discussed simultaneously. Any operation that can be achieved by array subscripting can also be done with pointers. The pointer version will in general be faster but, at least to ...
