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。

意思是对于非数组和指针类型的变量,不能用[]这样的下标符号。下标表达式,形如p[i],等价于*(p+i),其中+是指针加法,数值上相当于+ sizeof(*p) * i。“多维”的下标表达式如p[i][j],由结合性等价于(p[i])[j],即*(p[i]+j),也就是*(*(p+i)+j)。[]和一元*操作符的操作数...
