Programming Solution

cdecl as an FSM

#include <stdio.h>

#include <string.h>

#include <ctype.h>

#define MAXTOKENS 100

#define MAXTOKENLEN 64

enum type_tag { IDENTIFIER, QUALIFIER, TYPE };

struct token {

char type;

char string[MAXTOKENLEN];

};

int top = -1;

/ holds all the tokens before first identifier /

struct token stack[MAXTOKENS];

/ holds the token just read /

struct token this;

#define pop stack[top--]

#define push(s) stack[++top]=s

enum type_tag
