= '''Lab 8 Report''' =

'''Crazy!''' The parsetree.c file does not compile unless you fix a couple of errors here and there. '''Lab-8.c <-- its useless'''. OK, thats part of task 1 as well. Now, for the other tasks.

I really really say a big thank you to Braedon and Jason. They have corrected and fixed the most vital parts of the file that have made this lab possible! So yay for them!!

== '''Task 1'''==

Download parsetree.c file from the net. Task 1...DONE!

== '''Task 2'''==

To get the output of -(-(a b)), I first tried using the command to print 1+2 as in the handout. Then I simply modified the line to get the appropriate output. It worked!! :D

int main (void) {
ParseTree* t = mkNode( '-', mkNode( '-' ,mkNode( 'a', 0 ), mkNode( 'b', 0 ), 0) ,0);
prefix_tree(t);
return 0;
}

=='''Task 3'''==

Horrible horrible horrible. It took me forever to do this and here's my code for it!

int main (void) {

ParseTree* t2 = mkNode( '?', mkNode( '>', mkNode( '+', mkNode( 'a', 0 ), mkNode( 'b', 0), 0), mkNode( 'c', 0), 0),
mkNode( '*', mkNode( 'z', 0), mkNode( '+', mkNode( 'y' ,0), mkNode( 'b', 0), 0), 0), mkNode('?', mkNode( '=', mkNode( 'a', 0),
mkNode( '2', 0), 0), mkNode( '-', mkNode( 'x', 0), mkNode( 'y', 0), 0), mkNode( '-', mkNode( 'y', 0), mkNode( 'x', 0), 0), 0), 0);
prefix_tree(t2);

return 0;
}

=='''Task 4'''==
