let's say that the matrix you want is : int arr[4][3]; If you want to flatten it, you'll have this array : int arr[4*3]; If i and j are proper indexes of the matrix, then the translation would be : arr[i][j] - > arr[i * 4 + j]

int matrix[n_columns][n_lines]; for (size_t i = 0; i < n_columns; ++i) { for (size_t j = 0; j < n_lines; ++j) {cin >> matrix[i][j];} }
