Tokens are the basic elements of C programming, that are used for creating the correct C programs. Each and every smallest unit in C that is meaningful to the functioning of the compiler is known as a token. The compiler breaks the program into tokens and then proceeds further stages in ...
Because you're only doing the tutorial of the latter. A token is a small part of your code that your programming language can identify as a unit. For example if you write: x+y ... your language understands that x, + and y are three separate units (tokens) while if you wrote: x_...

intuitive understanding of what an API (application programming interface) is — but if you asked them to define it, they might have trouble putting an explanation into words. In simple terms, an API is both a piece of software running on a networked server and a component of programming ...
input, using a data structure called a parse tree or derivation tree. A syntax analyzer uses tokens to construct a parse tree that combines the predefined grammar of the programming language with the tokens of the input string. The syntactic analyzer reports asyntax errorif the syntax is ...
The parser expected the not token to be a part of the not in operator (because both == and not in operators have the same precedence), but after not being able to find an in token following the not token, it raises a SyntaxError.▶...
