Can i always use arrays without fixed length?

So, i tried to use 2 constructions:

int my_array[2] = {1,2}; and int my_array[]={1,2};

My code worked correctly in same times. Can i always use second way? In what cases i have to use fixed length of array?

you can only leave the length of the array out if you use an initializer, which is the part that has the curly braces and the values of the array inside (int my_array[]={1,2}). if you dont use an initializer, you have to provide the length of the array (int my_array[2];);
