As shown in the above representation, each cellE.g.R1C1 will hold the contents of the array. The number of elements present in a multidimensional array is the product of its dimensions. This means that if the dimensions of an array are 3×2 then the number of elements in that array is...
allowing to iterate over the bounds space (equivalent to the size of the c array_view) using the for_each algorithm. Dereferencing the iterator provides an index of each location in the space to the lambda expression, which is subsequently used to address data in the array_views. ...
Below are advantages of multidimensional array over pointer array: 1. Input can be taken from user 2. Faster access 3. Predefined size (Edit : source link of above is https://interviewmania.com/discussion/40015-c-programming-c-pointers) As I have heard that pointer is preferred over array ...

Another common use for pointers to pointers is to facilitate dynamically allocated multidimensional arrays (see 17.12 -- Multidimensional C-style Arrays for a review of multidimensional arrays). Unlike a two dimensional fixed array, which can easily be declared like this: int array[10][5]; Copy ...
std::vector takes care of all the memory it allocates. That is, if you clear vector< vector< int > > all the memory is freed (note that if you have vector< vector<int*> > you'll have to delete each int* yourself) Also, you may want to take a look at http://www.cplusplus....
