指向数组的指针(Pointer to an array).doc,指向数组的指针(Pointer to an array) If I have a definition int (* p) [3]; A pointer variable called p is defined, indicating that p is a pointer variable, which can point to a two-dimensional array of three int
int* arr1[8]; arr1 is an array of 8 pointers to integers. int(*arr2)[8]; arr2 is a pointer (the parenthesis block the right-left) to an array of 8 integers. int*(arr3[8]); arr3 is an array of 8 pointers to integers. This should help you out with complex declarations. He...
cout<<*(a+1);//2cout<<*(ptr-1);//5 数组名a本身就是指针,再加上个&就变成了双指针,这里的双指针就是指二维数组,&a+1,就是整体数组加一行,ptr指向a的第6个元素。 *A 可以看成一个(含有3个int元素的数组的)数组名,所以类推,去掉*,等于加上&, A是双指针,加1,就是数组整体加一行。
除非它是sizeof运算符或一元&运算符的操作数,或者是用于初始化数组的字符串文字,否则类型为“array of type”的表达式将转换为类型为“pointer to type”的表达式,该表达式指向数组对象的初始元素,并且不是左值。如果数组对象具有寄存器存储类,则行为未定义。 看起来像是a类型从array of int转移到pointer to array ...

classNSPointerArray:NSObject Overview The pointer array class is modeled afterNSArray, but can also holdnilvalues. You can insert or removenilvalues which contribute to the array'scount. A pointer array can be initialized to maintain strong or weak references to objects, or according to any of...
Although the integral value 1 is added to pIntArray, it does not mean "add 1 to the address"; rather it means "adjust the pointer to point to the next object in the array" that happens to be 2 bytes (or sizeof( int )) away. ...
