how declare 2d array in c++ using new? 20 answers

i java programmer. i'm trying fill array in win32 project

int **data::matrixinitialize() { int** mx = new int*[n]; (int = 0; < n; i++) { (int j = 0; j < n; j++) { mx[i][j] = 1; } } homecoming mx; }

but code throw exeption. please help me fill 2d array.

you miss allocation:

int **data::matrixinitialize() { int** mx = new int*[n]; (int = 0; < n; i++) { mx[i] = new int[n]; // missing line (int j = 0; j < n; j++) { mx[i][j] = 1; } } homecoming mx; }

but improve utilize std::vector or std::array.
