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.
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.
Program is not finished as I can't get passed read_data
Error: "error C2065: 'fin' : undeclared identifier error C2228: left of '.open' must have class/struct/union type is ''unknown-type''
#include "stdafx.h" #include <iostream> // for streams #include <iomanip> // for setw() #include <fstream> // for files #include <cstdlib> // for exit using namespace std; void read_data(int A[], int size)
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> class BinarySearchTree{ private: struct BinaryNode{ T data; BinaryNode *left; BinaryNode *right;
[Code] .....
and here is are the errors I'm getting from this header file.
1>------ Build started: Project: Programming Assignment 2, Configuration: Debug Win32 ------ 1> main.cpp : error C2143: syntax error : missing ';' before '*' : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int : error C2065: 'T' : undeclared identifier
I'm having some issues with my code. For the produce function i am getting an error saying 'no instance of overload function produce() matches the argument list' and also for the lines buffer[head].data = message; buffer[head].time = current_time i get an error saying 'expression must have pointer to object type.
In the code i'm not sure if i passed the variables to the function correctly. I have attached the code .....
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 :
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 .
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:
Code:
#include <stdio.h> #include <string.h> int main() {
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 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 am working on a couple C++ projectsfor my class. On one of my projects I get this error "identifier not found" for maximumValue. here is the code that I have done. I have got almost all the code from my text book..
// Three numbers.cpp : Defines the entry point for the console application.//
#include "stdafx.h" #include <iostream> using namespace std; int main() { // demonstrate maximum int value int int1, int2, int3;
