The terms "double", "int", and "string" are all types.

I'm assuming you meant to write "double" instead of "doubt", and "string" not "sting". :smirk:

Doubles, Integers and Strings all are datatypes, they descripe the "type" of data which a variable holds / is going to hold. If I am correct: The keyword "var" defines a variable with a first-dynamic datatype that gets set once the variable starts holding data. To me experience when taking userInput variables it is always good practice to not define the type first, unless you only want a specific thing to be entered.

Other languages might use "var" as you describe, but in C# an implicitly typed local variable is strongly typed just as if you had declared the type yourself, but the compiler determines the type. For example, the following two declarations of "i "are functionally equivalent:

var i = 10; // Implicitly typed. 
int i = 10; // Explicitly typed.
