A keyword is a reserved word, used by the programming language to establish actions or commands. For example, in the line:
while (value < 100) {
//block of code
}
"while" is a keyword, used to indicate iteration (loop) of what's inside the block of code.
variables are user-defined words that are able to hold values. In the previous case, "value" can be thought as a variable.

Difference between standard and user defined identifier?
A standard identifier is a reserved word. Keywords such as for, if, goto, return, continue, break, do, while, final, extern, static and so on are all reserved. Fundamental data types and modifiers such as void, int, char, wchar_t, double, float, long, short, signed, unsigned, const, mutable, constexpr and so on are also reserved. A user-defined identifier is any name (function, class, namespace or alias) that is not a reserved word.
