Token is the smallest element of a C program that compiler can recognize. The parser separates tokens from the input stream by creating the longest token possible using the input characters in a left–to–right scan.
The mikroC PRO for PIC32 recognizes the following kinds of tokens:
Tokens can be concatenated (pasted) by means of the preprocessor operator
##. See the Preprocessor Operators for details.
Token Extraction Example
Here is an example of token extraction. Take a look at the following example code sequence:
inter = a+++b;
First, note that
inter would be parsed as a single identifier, rather than as the keyword
int followed by the identifier
The programmer who has written the code might have intended to write
inter = a + (++b), but it wouldn’t work that way.
The compiler would parse it into the seven following tokens:
inter // variable identifier = // assignment operator a // variable identifier ++ // postincrement operator + // addition operator b // variable identifier ; // statement terminator
+++ parses as
++ (the longest token possible) followed by
According to the operator precedence rules, our code sequence is actually:
