fellow newbies, the internet says:
const is usually for single integers/settings
enum is for multiple integers/settings

I once heard about a city that never wanted to change. I think it was called...const-antinople 😎 In all seriousness, thanks for another amazing video!

Unfortunately is NOT true that the 3 kinds of constants availables in c++ are 'more or less the same' as suggested by this video.
And introducing 'enum' with only one member is really confusig the viewers about the pourpose of 'enum'.

You misspelled xylophone, but other than that, you have created great series, congratulations,

Constant? or const int? (read it out loud)

[brocklesnarufcchamp]

const and macro can make only a single variable constant. E.g. const int x = 1;.
But if we want to make several variables constant? Would it be cumbersome to jot down all of them? Wouldn't it be nice if we could make all those variables constant in one go? Well, that's where enum comes into play.
E.g. enum season { x = 0, y = 1, z = 2};.
There you go.

Dammit this brought the ptsd back with the rapid fire of constants and the tea bag of "So now you understand the to finish it off.

#define X 10 --> Is not same as constant variables. Its a macro which simply gets replaced. Both are little bit different ;)

I have a question can you only put integer types in enum or can you also put doubles

[kpcPrasad]

Question: Does compiler assign any datatype for a macro? If so, what datatype does compiler picks for #define macro??

I don't think your definition of "hungarian notation" is correct. For example, hungarian notation would be intAge instead of int_age.

Hi Caleb! Thanks for that, you really amazing in C++ programming, and thanks to you, now I can remember everything that the time did erase in my mind... Thank you again.
Man... There are something wrong here, I don't know if it was because I'm in Linux, but the compiler is ask me about declare enum. I'd correct it that way: enum test { y = 100 }.
Bye, now I will go to next video!

I like the music in the end of every video:)
