i am doing this program which is a parser calculator but when i compile it there's an error which is "FunctionTable funtab has initializer but incomplete type", i am using codeblocks 8.02, and my program is kinda long. I think my algorithms are correct and the only problem is in the syntax or how i coded it... here's a snipet of the main function

 c++ Syntax (Toggle Plain Text) 
#include "Parser.h"
 
const int maxBuf=100;
const int maxSymbols=40;
 
 
int main()
{
 
 
    char buf[maxBuf];
    Status status;
    SymbolTable symTab(maxSymbols);
    FunctionTable funTab(symTab,funArr);
    Store store(maxSymbols,symTab);
 
    do
    {
        cout<<">"; //prompt
        cin.getline(buf,maxBuf);
        Scanner scanner(buf);
        Parser parser(scanner,store,funTab,symTab);
        status=parser.Eval();
    }while(status!=stQuit);
 
    return 0;
 
}
#include "Parser.h"

const int maxBuf=100;
const int maxSymbols=40;


int main()
{


    char buf[maxBuf];
    Status status;
    SymbolTable symTab(maxSymbols);
    FunctionTable funTab(symTab,funArr);
    Store store(maxSymbols,symTab);

    do
    {
        cout<<">"; //prompt
        cin.getline(buf,maxBuf);
        Scanner scanner(buf);
        Parser parser(scanner,store,funTab,symTab);
        status=parser.Eval();
    }while(status!=stQuit);

    return 0;

}

its compiled as a one project, thats why it only had one header file, it is composed of 9 source files and 8 header files. i suppose that the problem is in the function table source file or function table header file...

should i provide a Link to the whole program? thank you very much...

int Size() const {return _size;}
int Size() const {return _size;}

This doesn't look right to me, you have the const keyword without a name.

Jabo, the const there indicates that when the method is called, it does not modify the object.

zip up the source and attach it

Thanks for the reply: here are the files
rs link:
PARSER.ZIP

You need to:

(Toggle Plain Text)

#include "Scanner.h"
#include "SymTab.h"
#include "FunTab.h"
#include "Store.h"

in either Parser.h or main.cpp

#include <cassert> in PTree.h

And there's an error in SymTab.cpp at line 54 about calling strcmp with 3 arguments. No doubt you meant to usestrncmp.

THanks a lot cache!!!! I am so STUPID!!!!!!!!!!!!!!!!!!! whoooo!!!! i just need to include those files.... and i checked the scanner.h header file... there's still some error in the ACCEPT method ill give it another check... thanks again... a big help
