In a C source program, the basic element recognized by the compiler is the "token." A token is source-program text that the compiler does not break down into component elements. Syntax
; token: : keyword identifierconstant string-literal operatorpunctuator The keywords, identifiers, constants, string literals, and operators described in this section are examples of tokens. Punctuation characters such as brackets ([ ]), braces ({ }), parentheses ( ( ) ), and commas (,) are also tokens.

∙ 11y agoIn software engineering, a token is commonly understood to be a segment of textual input data, separated from similar segments by one or more separators. For example, all text that is not a space, tab or newline character in C language code makes a token.
For example, this is a list of tokens, separated by semicolon: 123;321;ABC
The term token is frequently used in context with lexical analysis, an early stage in language compilers and interpreters.
A C compiler, for example, subjects the input (source code) to the preprocessor first. This removes all source code comments, makes "macro" substitutions and evaluates sections of conditional compilation.
The preprocessor's results are then subject to lexical analysis, which consists of separating the source into tokens, then classifying them into categories such as "keyword," "decimal number," "variable reference," etc.
The standard C runtime library also contains a strtok() API that helps breaking textual input into tokens.

What are the 6 types of c tokens?
A Token is the basic and the smallest unit of a programThere are 6 types of tokens in 'C'. They are:1) Keywords2) Identifiers3) Constants4) Strings5) Special symbols6) Operators
What is the token in c plus plus language?
A token in C++, and in many other computer languages as well, is the largest set of characters in the source code that meets the criteria of a single language element. Often, tokens are separated by white space, but if the context is clear, this is not required. The expression a=b+c, for instance, contains 5 tokens, a, =, b, +, and c. The expression a = b + c is identical in meaning. The "largest set" rule can be shown with the example a=b+++c. The tokens are a, =, b, ++, +, and c. This expression means to add b and c, store the result in a, and then increment b.

How do you get super fan swag tokens in adventure quest worlds?
you have to do the quests around the globe and the quests would give D or C (if you're lucky) tokens, then you go inside the house (the place next to the Johns and Drakath) and talk to the girl in the window. the girl will have two options, QUESTS or MERGE SHOP, the merge shop is where you go. This is where it get frustrating. 1. D to C token= 10 D tokens 2. C to B token= 10 C tokens 3. B to A token= 20 B tokens then with the A token you can complete the quests given to you by Malorie, or whoever, Some good quests that you could do is: 1. For Science (Drakath), i think you need upgrade to go to the lab though 2. the giant hamster wheel in the house, click in the middle of it 3. the catapult in the far left area 4. dunno... #2 and #3 is what i do
