How to use spaces in a "variable name"?

I have a very simple question but i just started learning C. I'd really appreciate if i could get some help because i'm trying to understand how the syntax works in the language.

What i want to do is something like this

    int Score1, Score2, "Final Score";

the error message i get is this:

    error: expected identifier or '(' before string constant

C, along with many other programming languages, don't allow any spaces, and some other special characters in variable names. You can however say something like: finalScore, or final_score

In general (and definitely in C), variable names must be valid identifiers¹ and cannot contain spaces or quotation marks.

Consider naming the variable finalScore or final_score instead.

¹ The syntax of an identifier is succinctly given in The C Programming Language (K&R), A.2.3 Identifiers:

An identifier is a sequence of letters [a-z, A-Z, _] and digits [0-9]. The first character must be a letter; the underscore _ counts as a letter ..

A variable name in C can contain any combination of alphabets, numbers and under-score (_). Any other special characters are not allowed in variable name.

Removing double quotes and using final_score or finalScore will work.

Also note that you can't have a variable name legal if it starts with a digit, although it can start with under-score
