Visual C++ :: No Circular References But Undeclared Identifier
Jun 11, 2014
Each of my header includes is protected by directives. I think I don't have to include Boolean in my work space because it is already included in the external dependencies section. and the Boolean.h is in the include path.
MachineShop, Boolean etc got undeclared identifier error
Tried to comment out the directives, to no avail.
Code:
#include <iostream>
#include <string.h>
#ifndef BOOLEAN_H_
# include "Boolean.h"
#endif
#ifndef PROCESS_H_
# include "Process.h"
#endif
#ifndef MACHINESHOP_H_
[Code] ....

I dynamically allocate a new list in the recMergeSort function which should run a constructor but when it get to the functions that use it, I get error C2065: 'otherHead' : undeclared identifier. I have tried setting it to NULL and it didn't work. I even copied the default constructor to a set function and I still get the errors.
Code:
template<class Type>
void unorderedLinkedList<Type>::recMergeSort(nodeType<Type>* &head) {
otherHead = new nodeType<Type>;
if (head !=NULL)
if (head->link != NULL)
[Code] ....
wonder if I'm sending the correct data type. Here is the heading of the functions that I'm using from the book.
Code:
void unorderedLinkedList<Type>::divideList(nodeType<Type>* first1,
nodeType<Type>* first2)

Why "Team" and "NUM_MEMBERS" are undeclared identifiers? I'm not sure I understand why it's giving me errors for those.
//Function Prototypes
void initialize (vector <Team> & tV, const int ID [],
const string m[][NUM_MEMBERS], int arraySize);
void printList (const vector <Team> & tV);
void menu ();
void add (vector <Team> &tV);
int search (const vector <Team> &tV, unsigned int size, int ID);

I get this error :
stra.c:54:29: error: "PS_index" undeclared (first use in this function)
and the function is
PS_Index = function(PS_index, indexData);
so what i am trying to do is :
first file:
Code:
#include <stdio.h>
#include <stdlib.h>
#include "stra.h"
int main (){
char name[] = "index.pif";
uint32_t i = 0;
[Code] .....
And header file:
Code:
typedef struct StraIndex{
uint32_t s;
uint32_t *i;
uint32_t *t;
}StraIndex; s
So first I would like to create my stra.o so i compile it as :
gcc -c stra.c -o stra.o
and then i get the above error. What would be the proper way to get a global structure inside my object.

I am developing a double linked list in C ( development environment ) is QT with mingw32 4.7 gcc / g++ compiler , in the header file I have defined struct as follows :
Code:
#ifndef LINKEDLIST_H
#define LINKEDLIST_H
#include <stdlib.h>
#include <sys/stat.h>
#include <signal.h>
#ifndef NULL
[Code] ....
When compiling I am getting the following error : 'NODE' undeclared (first use in this function)
and
each undeclared identifier is reported only once for each function it appears in
I have also attached the screen shot from the QT IDE
look's like the compiler is not able to pick up the definition of NODE structure , same happens in Netbeans IDE , interesting thing is if change the source file from c to cpp the error goes away .

Did a little Googling on this but couldn't find anything definitive. Is it safe to do something like
Code:
void MyClass::myFunc(){
my_type_t &foo = some_obj->get_member_reference();
store_for_later(&foo);
}
Then at some pointer later in execution, another function uses the pointer passed to store_for_later.

I have the following code segment:
Code:
void Swap(Number& num1, Number& num2)
{
cout<<"Before swap:"<<num1<<" "<<num2<<endl;
Number& temp=num1;
num1=num2;
num2=temp;
cout<<"After swap:"<<num1<<" "<<num2<<endl;
}
[code]...
to which the output is:
Code:
Before swap:13 11
After swap:13 11
13 11 that seems confusing.
why doesn't Swap() swap the two Numbers?

I am trying to make a utility program for work that will update multiple projects with local dll references. Basically I work with two solutions (for talk sake solutIon1 and solutIon2). Generally solutIon1 will reference the dll's built In solutIon2 which reside on a server. However for debugging proposes I sometimes need to D/L the solutIon2 projects and build them local-ally, so that I can reference the solutIon2 dll's local-ally (this Is so that I can easily attach the dll and step Into the code). However this require changing the reference paths, so that I am pointing to the local-ally built dll's, which Is quite a laborious task.
So the question is how would I update references in solution1 from the program that I am making. I don't really know what to start reading about as I have never done anything like this before.

I am attempting to combine two vectors into a vector of pairs. I want to be able to alter the first and second of each pair and have those alterations reflected in the original vectors. I thought the following code might work but get compilation errors about a lack of viable overload for "=" for the line with the call to std::transform:
void f()
{
std::vector<int> a = {1,2,3,4,5};
std::vector<int> b = {6,7,8,9,0};

I have an issue with a switch case in my program. I execute it and it does fine all the way up to where it says, "Answer (1, 2, or 3): ". When I enter 1, 2, or 3, it gives me' "Not an input choice!" from the default of the switch case.
NOTE: I use Code::Blocks on Windows XP.
Here is the code:

I am checking to see if two references are bound to the same object. My instincts tell Me, "Check their addresses. If they match, they are bound to the same." At the same time, I have not found anything in the C++ standard which would support this approach. Am I missing something? Is there wording which backs up My instincts? Is there a standard function to do this?

I have this basic prototype:
struct int_wrapper{int i;};
template <const int_wrapper&... IPack>
void display_all(const int_wrapper&, IPack...);
But when I try to compile it, the compiler says IPack is not a type on the last line. Are packs of references not allowed?

I have an assignment for uni which requires the program to ask the user to input a number in for a variable to use in later equations. The assignment specifies that if the number that is input into the program is not an interger that it needs to be rounded UP to the nearest interger. e.g. 2.5 = 3, 5.00001 = 6 etc. i have identified this variable using "int" which i know makes it an interger however it also always rounds the number DOWN to the nearest interger. I was just wondering what the best way to approach this problem was. The only idea i have is to put + 0.99999 at the end of this variable when it is worked out so that if it is not a whole number it will be raised above the next interger and then rounded down however this will not work if there is too many decimal places.
