Multi-character Tokens
If the input stream has been parsed into tokens up to a given character, the next token is taken to include the longest string of characters which could possibly constitute a token
- 根據以上規定，
y = x/*p會和y = x相等，而y = x / *p或y = x /(*p)代表y除以 value pointed py pointer p。 - 對於
y = x/*p，compiler 要如何決定/*是否為 comment 的開頭，還是 x 除以 value pointed by pointer p？
Strings and Characters
A character enclosed in single quotes is just another way of writing an integer
#include <stdio.h>
int main() {
printf("%d\n", 'a'); // 97
printf("%d\n", "a"); // 36765619
// warning: format specifies type 'int' but the argument has type 'char *'
return 0;
