Whats the difference? Pointer to an array vs regular array

Question

I\'m familiar with Java and trying to teach myself C/C++. I\'m stealing some curriculum from a class that is hosting their materials here. I unfortunately can\'t ask the tea

Answer 1

It is true that you can get most of array functionality by using a pointer to its first element. But compiler knows that a static array is composed of several elements and the most notable difference is the result of the sizeof operator.

sizeof(pointerArray) = sizeof int*

sizeof(array) = 10 * sizeof int
