this error is happening at the end of compilation I already posted something about it helped me include everything right in .he cpp
I discovered that for this error does not appear I have to change in cpp put TCHAR more if I do more error appears in the .cpp then he is char how do I corrigiri so I will let the three files containing this function I grasped C ++ now vlw

Reset your application properties to use ASCII rather than Unicode, or find a matching Unicode library for the Quark functions.

Go to Parentwhen they procure step QuarkInit ( TCHAR * connect) he did not correct me back the main error plus it returns these errors in my function and do not know how to fix

No, my support is confined to answering questions here. The problem is that you are mixing ASCII and non-ASCII constants and variables within your code, and confusing both the compiler and the linker. Take a look at What are TCHAR, WCHAR, LPSTR, LPWSTR, LPCTSTR (etc.)?[^].

It is not a compiler error but a linker error telling you that the function QuarkInit() called from within the file main has not been found in any of your compiled files or libraries.

It it is contained in a library, you must add that library to your project. If it is located in some of your source files, check for correct spelling and parameter types and that the file is included in your project.

TCHAR and the _T() macro are extension used originally by the Microsoft compiler (Visual Studio). With mingw, you must include tchar.h and use an additional linker option when building an Unicode application (see http://sourceforge.net/p/mingw-w64/wiki2/Unicode%20apps/[^]).

You probably want to start Here[^]

Normally, when one says ping, that means sending icmp-echo packets and listening for icmp-reply, which requires root privileges, so keep that in mind when developing your solution.

Good luck.

C++

struct node{
    int key;
    node* head;
}

node *head = NULL;
void func(node* &h,int n, int m) 
{ 
   if(n > m) 
     return;
   else {
        int mid = (n+m)/2;
        func(h->head,n,mid-1);
        func(h->head,mid+1,m);
   }
}

I am wonder what is the difference of parameter:
func(node* &h, int n, int m)
and
func(node* h,int n, int m)

what is the usefulness of node *&h.

It is a pointer to a reference. You can modify the pointer itself rather than the object that the pointer is pointing to.

Please forgive me if I'm wrong, but isn't it a reference to a pointer, instead?

Possibly. I've actually never used either (if both are valid concepts) so I could be wrong.

Richard MacCutchan23-Sep-15 22:38

Pointer to reference is not valid, since a reference is not an object.

C++

func(node* &h, int n, int m)

h is a INOUT parameter, if func changes h then the caller see the changed value (that is after function execution, h could point to another address).

C++

func(node* h,int n, int m)

h is a IN parameter, if func changes it, the caller doesn't see the changed value.

That error is telling you that the linker cannot find the implementations of the three functions named in the error messages.

See: LNK2001[^]

Are you calling functions that you haven't implemented? This error can happen if you include a header (.h) file without also having the implementation (.cpp) file as part of the project.

You have most likely failed to include the library that contains these functions. Check your project settings.
