C 语言实例 - 使用指针访问数组元素 C 语言实例 使用指针访问数组元素。 实例 [mycode3 type='cpp'] #include int main() { int data[5], i; printf('输入元素: '); for(i = 0; i < 5; ++i) scanf('%d', data + i);..
第七行,int *p = ia;若以數學角度,p和ia是相等的,而p是pointer,ia是array,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...

如果,将括号加于方括号前,char (* argv)[]这样就是数组指针,Pointer of Array。 所以,不考虑初始化的前提下,argv 其实就是一个双重指针,但是,又不能将它等价看作char **,这解析为一个指向字符指针的指针,它们两者的区别主要体现在以下代码片断的初始化的过程中。char *argv[]需要一个地址列表来初始化,而cha...
If the return type of the method is the annotated interface, it is an address computation for an array access. Calls of the method are replaced with address arithmetic. The possible signatures are PointerType addressOf(IntType index); The receiver is the pointer that is accessed, i.e., ...
