  1. one last cfg-production to finish yacc project

    Hello everyone, I have a production that is giving me a problem. It turns out to be an array element. I have been given what my output of the AST should be and is as follows:



    begin
    real
    ...
  2. I figured it out. Begin needs to be in the token...

    I figured it out. Begin needs to be in the token declaration with a value:


    %token <i> Ident 1 IntConst 2 Begin 6
  3. YACC abstract syntax tree error: line 47: fatal: must specify type for Begin

    I am working on a YACC file for a compiler independent study. I have received the above error. I am pretty sure the way I am starting off the tree is incorrect and I am not sure how I would correct...

    yes and the problem was a semicolon at the end of the while loop in the scanner code. I inadvertently added one. Habit of the "pinkey" finger.

    printf("%c\n", nextChar);

    Produces the same results.
  6. Passing a file pointer to a function is producing undesired output

    Hello everyone,
    I am working on a project and decided to try something simple before I start adding items. I am calling a function from main and that function has a file pointer. Here is my main.cpp...

    Sorry oogabooga, he explicitly states, "Building the tree (through one function) should be implemented in another source file buildTree.c"

    You are correct, they are not fuctions. I did not word that correctly. The interfaces I am allowed are:


    node_t *buildTree(FILE *)
    void traverseInorder(node_t*)
    void traversePreorder(node_t*)...
  9. I am not allowed any other functions. I have...

    I am not allowed any other functions. I have created a binary tree and completely agree the recursive approach would be much better. But how do you call an interface of:


    node_t *buildTree(FILE...
  10. Unfortunately I am not allowed any other...

    Unfortunately I am not allowed any other functions. I can only have main.c, buildTree.c, traverseInorder.c, traversPreorder.c & traversePostorder.c.

    I believe that is what I am asking. To clarify my file will contains strings like

    So are you saying:

    or just

  17. warning: return makes pointer from integer without a cast

    Hello all,

    I have a function that I want to exit gracefully when an "error" occurs in an input file. My function declaration is:
