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''

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;

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
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)

wonder if I'm sending the correct data type. Here is the heading of the functions that I'm using from the book.
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.
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.
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?
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?).
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 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 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;
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;
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.
