Why "Team" and "NUM_MEMBERS" are undeclared identifiers? I'm not sure I understand why it's giving me errors for those.

//Function Prototypes

const string m[][NUM_MEMBERS], int arraySize);
void printList (const vector <Team> & tV);
void menu ();

C++ :: Binary Search Tree - Undeclared Identifier

Mar 8, 2013

I'm trying to create a template binary search tree and I'm getting all these vague errors that I have no clue how to solve. I've narrowed it down to my findMax and findMin functions but i can't figure it out any further than that.

template<class T>

BinaryNode *left;
BinaryNode *right;

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_

Visual C++ :: New Linked List Error - Undeclared Identifier

May 30, 2013

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)

C++ :: Value Assigned To Int Variables?

Feb 6, 2013

Suppose x, y, and z are int variables. What value is assigned to each of these variables after the last statement executes?

x = 4; y = 11;
z = y - 2 * x;
x = z + y;
y = x + 5 * z;
w = x - y + 2 * z;
x = y + w - x;
-w;

C++ :: Does Int Vars Automatically Get Assigned (0)

Feb 13, 2015

I am wondering if integers and unsigned integers automatically assigned to zero (0) upon declaration like so:

bool randomFunction() {
int i;
if (i == 0) {
return true; //Will most modern compilers return true here?
} else {
return false;
}
}

I am just curious as I have always initialized my ints/unsigned ints variables. Would save me a lot of typing if I didn't have to do this all of the time.

I know that floats and doubles you still have to initialize.

C++ :: Variable Assigned Wrong Value?

Nov 15, 2012

Consider the following:

Code:
float foo( float const *bar )
)
{
float temp;
temp = *bar;
...
}

Something I am noticing is that temp right after the assignment to *bar, is not the same value as *bar. This is for a project at work and the code runs on an embedded board with an ARM processor. I've copied the function into a standalone program for both Visual Studio and Code::Blocks and it works correctly there.

C++ :: Getchar - Return Assigned Value

Nov 9, 2012

Once again i hit a very simple problem i am unable to resolve. I using Visual Studio 2010, but am compiling for C.

This:

Code:
char i=45;
while(i=getchar() != EOF)
{

should imo work perfectly (yes, no real code, just to demonstrate the issue), but it doesnt. Getchar() always returns 0x01. Why is that? This, in contrast, works perfectly fine:

Code:
char i=45;
while(i!= EOF)
{
i=getchar();

Shouldnt an assignment always return the assigned value?

C :: Error Including Undeclared Structure

Aug 11, 2013

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.

C/C++ :: Passing Var Assigned In A Class File To Functions Outside Of Int Main?

Dec 7, 2014

I'm trying to pass the value of an object created from a class file to a function outside of the "Int Main" function in the main.cpp file. I've successfully created the object, I just want to pass it to a void function but I'm getting the scope error below. I'm not sure how to correct. I'm not having much luck with research either (static variables?).

error: 'TicTacToe' was not declared in this scope

main.cpp
#include <iostream>
#include <cstdlib>
#include "Signature.h"
#include "Gameplay.h"
using namespace std;
// Initialize array
char square[10] = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9'};

C++ :: Double Linked List - Node Undeclared

Apr 2, 2013

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 .

C :: Rounding Of Numbers Using Int Identifier

Apr 23, 2013

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.

I need to keep a data structure, which has an id, an object pointer and a position. this id is used to randomize things, the object and the position is attached to this id. So which way is better?

Code:
struct data {
int id;
ObjectBase* obj;
Vector3 position;
};
vector<data> vecData;

or

C++ :: Incorrect Operands And Undefined Identifier

Apr 25, 2013

I'm writing a program to read in a Master.txt file and then update it through a Transaction.txt file that contains various transaction types [Adds (A), Deletes (D), and Edits (E1-E4)]. The records in both files are in ascending order based on Item#. Ultimately, the original Master.txt and updated Master file (Master2.txt) will be merged to reflect all valid transactions, and an errorLog.txt file will be created to indicate all invalid transactions. I feel I have all of the code written correctly, but I am still getting errors on my operands and identifiers.

#include <iostream>
#include <fstream>
#include <string>
using namespace std;
struct invRecord {
string delDate;
