WebDec 18, 2024 · #include int main () { const size_t SIZE = 10; int arr [SIZE]; int * ptrLastElement = arr + (SIZE-1); // Populate the array, arr, using int iterator for (int i = 0; i = 0 ; ++curr) { std::cout << curr << "\t" << *curr << std::endl; } return 0; } … You can only cast to a type that is known at compile time. What you can do is convert to a pointer to first element of the first row: int* p = static_cast (tab1);. You can then treat the array as one dimensional 1. Converting two dimensional indices to one dimensional requires some trivial math: x, y -> x + y * i.

WebMay 5, 2024 · Arrays in C++ must have their size defined at compile time. There is simply no way around this. Strictly speaking, this is not correct.
