I would say I’m pretty new to this but could someone explain the basics about data types, more specifically Integers, characters, boolean, string and floating-point numbers.

I would say I’m pretty new to this but could someone explain the basics about data types, more specifically Integers, characters, boolean, string and floating-point numbers.
Types or datatypes say what kind of information you are able to store in a variable.
It is like you will assume that you have in your pocket a wallet with datatype “money”, thus you are able store “money” there but not “keys”.
Example datatypes:
Integer can store whole numbers:
5
12937
1298273
can’t store number with fractional part:
123.43
234.534634643
12452352.1235
can’t store strings:
“hello”
“nice to meet you”
floating point can store whole number and this with fractional part:
5
12937
1298273
123.43
234.534634643
12452352.1235
can’t store strings:
“hello”
“nice to meet you”
Characters can store single chars:
“a”
“n”
“d”
can’t store whole strings:
“hello”
“nice to meet you”
Boolean can store logical values, logical value answers the question if something is:
True
False
Physically booleans can be represented in different wayy: True could be 1 or any value except 0 and False can be 0 (like in C like languages)
