Whats the difference between these two?

Question

const int SIDE;
SIDE = 10;

And

const int SIDE = 10;

Answer 1

hello Dark AR

const makes a variable constant,

i.e. const int side
side = 10;//will give error, it’s constant you cant declare const with the declaration

now you can do,

i.e. const int side = 10; // this is true

Answer 2

A constant should be initialized at the time of declaration because it can not be re-initialized.

First one will give you error, second will not.
