c++: "expected unqualified-id" newbie errors
 
This is FinancialProductsManager.cc:

Code:
#include "FinancialProductsManager.h"
#include <iostream>
#include <string>

using namespace std;

FinancialProductsManager::bool insertProduct(string fproduct, double value)
{
   
}

FinancialProductsManager::bool removeProduct(string fproduct)
{
   
}

int main(int argc, const char* argv[])
{   
    //cout << "testing the FinancialProductManager" << endl << "---------------------------------------------------";
   
}
and this is FinancialProductsManager.h:
Code:
#ifndef _FinancialProductsManager_H
#define        _FinancialProductsManager_H 

#include <hash_map.h>
#include <string>

using namespace std;


class FinancialProductsManager
{
   
    private:
        hash_map<string, int>  _financialProducts;
       
       
    public:
        bool insertProduct(string fproduct, double value);
        bool removeProduct(string fproduct);
}

#endif
When compiling with g++, i get

What's the problem?

There are a few errors, I might miss some because I just woke up.

So let's see

First .. in your .h file you're missing a ';' (semicolon) after the class declaration (e.g.: class X { .... }; )

Also the way you define your methods is wrong, the right way is:

return_value ClassName::methodname(params) {}

so where you have
Code:
FinancialProductsManager::bool insertProduct(string fproduct, double value)
{
   
}
you should change to:
Code:
bool FinancialProductsManager::insertProduct(string fproduct, double value)
{
}
The same goes for FinancialProductsManager::removeProduct

On another note if you do "using namespace std" in the header file ... you don't need to do it also in the .cc files that include it

Hope this helps ...
Cheers!
