A proper way to create a matrix in c++ - Stack Overflow
Make your own matrix class, that way you control every last aspect of it, including range checking. eg. If you like the " [x] [y]" notation, do this: std::vector<std::vector<bool> >m; my_matrix(unsigned int x, unsigned int y) { m.resize(x, std::vector<bool>(y,false)); class matrix_row { std::vector<bool>& row; public:
C++ Multidimensional Array - GeeksforGeeks
2023年8月22日 · Multidimensional arrays are arrays that have more than one dimension. For example, a simple array is a 1-D array, a matrix is a 2-D array, and a cube or cuboid is a 3-D array but how to visualize arrays with more than 3 dimensions, and how to iterate over elements of these arrays? It is simple, just

Multidimensional variable size array in C++ - Stack Overflow
2009年12月22日 · You need to declare the matrix var as int* matrix, as a dynamic array is declared as a pointer. But you can't do a 2d array in one new with both dimensions being variable. You can do a 1D array and do the indexing math on your own. int* matrix = new int[x*y]; // Set element x1,y1 to 5 matrix[x1+y1*x] = 5;
