I have the following problem, I have an object of a class Subject, and I want that this object points to another object of class Classes, creating a kind of link. How can I do that?
View 4 RepliesI've copied and pasted my code. The main program, the calculateTaxes.cpp function code and my makefile. I am using the makefile to link these two codes together but I get an error when I type 'make' in the command line.
I receive the error code:
assign2c.cpp.text+0x169): undefined reference to 'calculateTaxes(float, float, float*, float*, float*)'
collect: ld returned 1 exit status
make: *** [main.exe] error 1

I am new to programming for starters. The problem I am having is linking a sub .c file to my main.c I am assuming I will need to use #include <insert_sub_file.h> correct?

How do I link the strings to the integers?
declare
int *p[3];
that gives an array with 3 pointers, but how 3 pointers can have a link in the memory?
The sample output of this program would be:
Please select:
1 - Year
2 - Day
3 - Month
Input choice: 1
Input Number: 2
I'm a Sophomore!
Please select:
1 - Year
2 - Day
3 - Month
Input choice: 2
Input Number: 2
It's Tuesday.
Please select:
1 - Year
2 - Day
3 - Month
Input choice: 3
Input Number: 2
February. Heart's month!
Here is my code, I only typed the Year(levels) yet because when I tried to input 2(day) and 3(month) for the Input choice and after that, Inputting a number to 1-4 would yield the same result to case 1's year levels.
#include <stdio.h>
#include <conio.h>
using namespace std;
[Code].....
how to link the case 2 to days and case 3 to months?
I've recently integrated a scripting functionality into my game engine (squirrel), but I can't figure out how to dynamically link the library.I have to dynamically link some libraries for licencing sake, but I'm forced to statically link Squirrel. How can I statically link Squirrel, but dynamically link the others?

I am trying to take the Array v[]={0,1,2,3,4,5,6,7,8,9} and put some of the numbers together so I can create a math problem. I have used next_permutation to get the possible combinations of the numbers. I am trying to check every combination to see if they work. Like v[1]v[2]v[4]v[0]v[3] to get then number 12403 (that is where I am having the problem) that I can subtract from v[7]v[2]v[0]v[1]= 7201 to get the answer 5202. How can you put v[1]v[2]v[4]v[0]v[3] together to get the number 12403?
View 1 Replies View RelatedI'm getting a massive 1300 char link error with VC10. It appears to complain that it can't see the constructor although the constructor is definitely there.
Error:

However, the constructors seem to be there and if I copy them into my program just to make sure - the compiler complains that they are already defined:
namespace BinarySearchVector {

public:

Any clues as to what I'm missing ?
how to enqueue time. An example is Code: pqueue.enqueue("Name", 11:00); But it will read an error because the ( : ) is there. So how can I do it so that I can output time.
Desired outpout:

How can I use one external library in my C++ program?
View 3 Replies View RelatedI'm building an app using VC++. The app links to a DLL built using TDM-GCC (which uses MinGW I think). Obviously, the DLL comes with a link lib.
If the lib is linked to another MinGW app, the DLL functions get found by name. So if the DLL builder updates his DLL, the MinGW app carries on working.
However, if the same lib is linked to a VC++ app, the functions get found by ordinal value. But MinGW doesn't seem to have any means of guaranteeing that a later build of the DLL will use the same numbering scheme. So his new DLL will break the pre-existing VC++ app that used it.
In VC++ this problem could be solved by using a DEF file but that doesn't seem to work in MinGW. So my question is:- can a DLL built with MinGW be somehow instructed to export its functions only by name - or at least to export them so that any other compiler will import them by name and not by ordinal numbers?
I did some of the projects using STL container and it is pretty much efficient to retrieve the data's information quickly (i.e. sets, sets & maps). I read many C++ OOP book and none of them make me clear about the Link Between (STL) Container and (Fstream) File I/O. Can they link together ?
I am going to design a small Library Book Management Project. I am planning to develop it using the STL Algorithms & containers. Objective of this project is to keeping the records of books issued and deposited by students in a particular date. User will be given a facility to retrieve student's information, book information and he/she can modify/update specific book's, student's information by changing issue date, deposited date, Book's publication etc.
My intention is to create a File I/O where user can input & update/modify daily transaction inside the file called (xx.dat) file in project directory. Is it possible to create 'set' container inside the file (xx.dat) ? Or, It's impossible ? Or, do i have to do this in other way?
i write this program and every things work correct except when i want to add data of file to the link list .when i add the data to the link list by add_to_linked_list() every things work correct but when i use read_linked_list_from_file() it doesn't work
Code:
#include <stdio.h>
#include <stdlib.h>
// double linked list structure
struct linked_list {
struct linked_list *next;
struct linked_list *prev;
char *value;
};

I have a VC solution . This solution contain 1 execute project and 10 library projects. The libraries added to the execute project by
#pragma comment(lib,"../outputbin64/lib/mylib").
When i comment these lines to not be added these libraries to the execute project , i will have link error like this :
LINK : fatal error LNK1104: cannot open file '../outputbin64/lib/mylib.lib'
My library projects not added to execute project with another way.
My question is why the execute project will link the libraries that not added to project programmatically?
I have to create a 2D link list with 2 level hierarchy
some thing like that
Code:
head nodes level 1: 0 1 2
/| / /|
Sub node level 2: 0 1 2 0 1 0 1 2
Real Data under |
each sub node: |
int **join=Null;
int unique = 0;
int col;
int ptr;
int *tmp_perm=Null;
int col_elem;
I know how to deal with 1 level link list structure. But i don't know how to access, delete, nodes and sub nodes from this 2 level hierarchy. C
I'm getting unresolved link errors when I attempt to compile.

In Report Automattically linked based key.
but report data not showing
I created a dataset that contains an empty dataTable that has several columns , and then I created a new report that is linked to this datatable using the report wizard. In my form there is a button when clicked should fill the datatable mentioned above ( I checked if it is being filled by displaying its content in a dataGridView and by firing a messagebox that is triggered when 'datatable.rows.count > 0' ).
The reason that the datatable is initially empty is that it depends on some conditions that may alter the query used to fill it.
But finally when I load the form that has the report viewer it only has the names of the columns of the datatable and no contents. What's wrong ?
How do you programmatically expand a url link to its true location?
Do you know about tinyurl.com and baidu.com? Baidu.com is a search engine that tries to discourage people from using their web site to make metasearch engines by hiding their links in a way that is a lot like how tinyurl.com works. TinyUrl.com is a web site where, if you want to present someone with a link to something and that link is long, you can use tinyurl to produce a tiny url for presentation purposes.
Anyway, what I want to do is to find a way to programmatically take the link [URL] (the first link in a search for Jessica Alba using baidu.com) and have it return the actual link, [URL] . That is just one example. What I want to do is not specific to Jessica but for using Baidu.com as part of my group of search engines in my meta search eneing project.
Maybe there is a way of using the WebBrowser class but I did not see a member that was the URL.
Maybe there is a way of using WebRequest and WebResponse.
