Chapter 2: Arrays, Character Sequences, Pointers, Dynamic Memory, Data Structures,

Can arrays in C++ store multiple types?

No, they can only store a single type.

How can we initialize all the values in the following array to 11, 12, 13, 14, 15?
int foo[5];

int foo[5] = {11, 12, 13, 14, 15};

How can we partially initialize the values in this array to 11, 12, 13?

int foo[5];

int foo[5] = {11, 12, 13};

When we partially initialize an array, what happens to the other elements?

int foo[5] = {11, 12, 13};

All of the other elements are automatically initialized to 0 by C++.

How can we initialize every element in this array to 0 without writing the zeroes explicitly?

int foo[5];

int foo[5] = {};

What happens in the following array, where we didn’t mention a size?

int foo[5] = {11, 12, 13, 14, 15};

This contains no size, so the compiler just realizes that there are 5 values, and behind the scenes, it automatically creates int foo[5];

Ended on Slide 7, Week 2 special members (you can kind of skip this whole chapter and be fine, because it’s identical to other languages).
