int**其实和一级指针一样 int a=100; int* ptr=&a; int** pptr=&ptr; a的物理地址是:0x000000D64BDCF5F4 { a的值为0x100 } ptr的物理地址是:0x000000D64BDCF618 { ptr存储的地址是:0x000000D64BDCF5F4 a的地址 } pptr的物理地址是:0x000000D64BDCF638 { pptr存储的地址是: 0x000000D64B...
In twoDimArrayDemoPtrVer.c you see two ways of passing 2-D array to a function. In first function array_of_arrays_ver array of arrays approach is used, while is second function ptr_to_array_ver pointer to array approach is used. ...

high: this pointer will point to the index of the greatest element, in a sorted array it will be the last element of the array. low = 0 high = len(arr) - 1 # as python follows 0-indexing Step 2. Check elements at both pointers ...

In above example, I have a 2D arrayabcof integer type. Conceptually you can visualize the above array like this: However the actual representation of this array in memory would be something like this: Pointers & 2D array As we know that the one dimensional array name works as a pointer to...
In this approach, we will compare the two strings using pointers. Algorithm to compare two strings using pointers: Step 1: Start the Program Step 2: Input both the Strings Step 3: Declare function compare() which takes a pointer to the first character of both strings. ...
