Rick (rbha033) and I (mgha023) worked on the lab together...Joint effort:P. Well, this is how far we got. Unfortunately, after much toil, we were dissappointed that it didn't work:( ... Our reflective lab essays are on our respective individual wiki pages...

Code we had:

Tree* Stmt( TokenStream* tokens ) {
Token n = current(tokens);
Tree* t1,t2,t3;
if( eqToken(n, TOK_IF)){
Tree* t1 = Exp( tokens, 0 );
advance(tokens);
expect(tokens, TOK_THEN);
Tree* t2 = Stmt( tokens );
advance(tokens);
expect(tokens, TOK_ELSE);
Tree* t3 = Stmt( tokens );
}
// return mkNode3(TOK_IF, mkNode(t1,0), mkNode(t2,0),mkNode(t3,0),0);
//return mkNode3(TOK_IF,t1,t2,t3);
return mkNode1(TOK_IF,t1);
}

Error we got after compiling it:

H:\ec250\lab9>gcc *.c -o parser && .\parser.exe
parser.c: In function `Stmt':
parser.c:157: error: incompatible type for argument 3 of `mkNode3'
