PROBLEMS!
- Took quite a while reading through the pdf, and very confused afterward.
- After choosing option 1, very confused as what I'm suppose to do, so I looked at the toy_tokeniser and decided, this could be it! (copy & paste = win!)
Approach
- After reading through toy_tokeniser and tokenise.h, and came to a great realization of what to do! Flesh out all functions in toy_tokeniser! and rewrite them to a PROPER tokeniser.
- Started with eqToken() function, and below is what I've came up according to the constraint:
bool eqToken( Token a, Token b ) { if (a.type != b.type) { return false; } if (a.type == T_INTEGER) { return a.val.intval == b.val.intval; } else if (a.type == T_FLOAT) { return a.val.fltval == b.val.fltval; } else if (a.type == T_IDENT || a.type == T_SYMBOL) { return a.val.symval == b.val.symval; } else if (a.type == T_STRING) { return a.val.strval == b.val.strval; } //T_END and T_NOTHING are treated equal return true; }
- Rest of the function beside, void init_predefined_tokens( ), seen correct to me... confused again due to the lengthy lab notes and it's this easy?
- So continue onto void init_predefined_tokens( )...
- After reading through the pdf nth time, with no mentioning of init_predefiened_tokens is suppose to do, I logged off.
CONCLUSION SO FAR
Very confusing lab, very confusing indeed....
TO BE CONTINUE....
