can anyone explain "VARIABLES" in a simple way

Question

the " VARIABLE " section in this app is kinda of understanding and confusing me a bit...
Can anyone explain it in easy way ?!

Answer 1

You can think of a variable as a tiny box, with its name written in the side. It can store only one "thing" at a time, no more. For example, a variable can be of type int, thats an integer, so it can store (it depends on the machine, but lets use default for simplicity) values from -2million to +2million, just one number at a time
Variables can be initialised, "overwritten" and can be of a lot of data types. Here are some examples:
1. (will use C-like language)
int a = 25.
Int the box you will have 25, now:
a = 15
In the box, you no longer have 25, its gone forever, you have 15

Variables can be of a lot of data types: long int, short int, double, float, String, Array, boolean, char, and even user-defined data types.
Also, each variable, when created, is placed somewhere in memory, at a certain ADRESS. Not that important to know for now, but useful.
