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 inte
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。
