The correct way to initialize a dynamic pointer to a multidimensional array? [duplicate]

Answer 1

Another approach would be to use a 1D array as an 2D array. This way you only have to allocate the memory once (one continous block);

int *array;
size_t row=5,col=5;
array = (int*)malloc(row*col*sizeof(int)) //or new int[row*col]

This would result in the same as "int array[5][5]".

to access the fields you just do:

array[1 //the row you want
 * col //the number of columns
+2//the column you want
] = 4;

This is equal to:

array[1][2];
