C/C++ :: Placing Struct Of Object In Header And Source File?
Jul 19, 2014Let's say I am using a library containing classes called class1 and class2 but both classes take three arguments to construct them. eg. class1(int a, int b, int c). and the same for class2
The below is an example of how to lay out the structure in the header and source file if class1 and class2 don't have any arguments in their constructor. But.... I'm not sure how to go about the below to take into account the constructor arguments of class1 and class2.
program.h
struct thestructure
{
thestructure(class1, class2); //constructor.

C :: How To Generate List Of Struct Members Using Header File As Input
Jun 25, 2014I need to create a list of all members of a struct using the sturct definition as input. The struct is NOT part of the program, but is the input to the program.
The struct that I am using changes over time as features are added. I need the complete, fully qualified field names to then generate a table with all names with their offsets, type and length.
This information then allows me to create readers of the data that will run on different architectures, compilers and operating systems.
The struct currently has 800+ lines and uses typedef and embedded structs.
Perhaps this could be done creating LEX, YACC, Perl, SED, AWK or other language system.
C++ :: Include Function From Header File?
Feb 21, 2013I am trying to include a function from a header file named headerfunt.h . The code of my header file is

C++ :: Passing Struct Array In Function

You should be able to enter those fields, and after some time when while loop is stopped (when u press n) it should print out that PhoneBook bellow. I don't understand what is the problem but I think it is that Display function.
C++ :: Defining Function Prototypes In Header File Without Implemented Body
Oct 6, 2014Basically, I have made a program which implements the platform specific layers (such as entry function, file loading, timing functions etc.) that gets compiled into a .exe (or platform equivalent).
But I want to make this portable and reusable across other projects, so the entry function for the platform will call the function "AppMain" which is the generic main function that is not reliant on the underlying platform etc. (i.e defined in a .h file that the project module will implement).
Ideally I would want to build the AppMain code into its own library. However, This AppMain code would want access to the Platform functions such as the functions compiled into the .exe.
This has confused me somewhat and has forced me to build both the AppMain module and the Platform Code into the same exe file so they can use each others functions.
Is there any way I can create a header file (with all the function prototypes in) but they do not get implemented in the Platform code but rather they can be 'guaranteed' to be available at runtime?
Here is what I am trying to achieve in a high level view:
win32layer.cpp: (implements all the functions defined in Platform.h)
#include <AppMain.h>
int main(int argc, char** argv) {
//call AppMain
return AppMain(argc, argv);
[Code] ....
in this scenario of course I could not compile the platform functions as the application has not been created and thus appmain cannot call the platform functions because that has not been created etc....
Any way to overcome this?

C++ :: Calling A Function From A Header To Another Header?
May 16, 2014I'm doing a compiler, and I'm using writing everything in headerfiles.
at the moment I have lexer.h, token.h and for this case I need reservedWords.h
reservedWords.h is made up of enums showing the needed words
in token.h I have a function called reservedWords reservedLookup(string str) which returns a reservedWord (enum)
now in lexer.h I have a function called Token* getNextToken() in which I need to make use of the function reservedLookup found in token.h
note that all of them are classes apart from reservedwords as in
class Lexer
{
public: .....
}
class token
{
public .....
}
how I can call that function?
I tried declaring reservedWords reservedLookup (string str) BUT obviously it's directing me as Lexer::reservedLookup and not as Token::reservedLookup
When I tried using Token::reservedLookup it gave me
E:Universitycompilerslexer.h|65|error: cannot declare member function 'Token::reservedLookup' within 'Lexer'|
N.B I use namespace std, that's why I didnot write std::string str
C :: Reading Lines From A File And Storing It In Array From Typdef Struct

C++ :: Call To Member Function X Is Ambiguous - Overloaded Member From Header File
Feb 23, 2014I get the following error in XCode whenever I try to access the member I created 'randomGen' in a separate class in a different header file. I have made sure to include the header file and have tried to access it through an object.
This is the code I enter when trying to access the method from randomiser.h in main.cpp. It is also an overloaded function with doubles and integers:
RandomG randomiser;
randomiser.randomGen(); // 'Call to member function 'randomGen' is ambiguous'
This is the code inside randomiser.h:
#include <string>
#include <iostream>
using std::string;
using std::cout;
using std::endl;
class RandomG {
[Code] ....
This is the error inside xcode: [URL] ....
I have tried seperating the code for the functions in another class (main.cpp) and then running and it seems to works, so I'm not sure why I can't put everything in the .h file and then access it?
I would like it in a seperate file so it doesn't clutter my main. I am writing a game with SDL so that might be confusing and I would like the window to have a random title and other random properties, so it would be easier to use a function.
C++ :: Implementation File Versus Header File - Eclipse Giving Errors
Feb 10, 2013I have written my program and it works when I keep everything in the header files, and then have my main. I am now splitting them up into implementation files, but Eclipse keeps giving me errors. It gives me error at every opening brace of the constructor and functions. It says on all of them "Redefinition of (name of constructor or method), Previously declared here." What am I doing wrong, because it works in the header file?
#include "KeyValuePair.h"

C++ :: Splitting Template Class To Header H File And Implementation CPP File
Sep 12, 2014What is the right syntax for implementing the .cpp of a template class?
Consider this LinkedList.h file:
Code: #include<iostream>
#include"Iterator.h"
template <class T>
class LinkedList {
[Code] ....
How should the implementation for the LinkedList constructor, for example, should look like in the LinkedList.cpp file?
I tried this:
Code: #include "LinkedList.h"
template <class T>
LinkedList<T>::LinkedList<T>() {
// constructor
}
LinkedList<T>::~LinkedList<T>() {
// destructor
}
But the compiler wouldn't accept it.
C++ :: How To Declare Class As Forward In Header File - Regular Use In CPP File
Jan 17, 2015lets say we have a valid class with full implementation, X. can this class be declared as forward in Y header file:
Code: class X;
class Y{
X* m_X;
}
but still be used as regular in the cpp file?
Code:
#include "Y.h"
#incldue "X.h"
T Y::function(){
m_X->doSomething();
}
visual studio prevents me from doing it , I wonder if the standard also says so.

C :: How To Share Variable Value From One Source File To Other Header File
Dec 11, 2014I wanted to share the value of a variable from Sender Program to Receive after program and want to calculate difference between send and receive. After studying Header file concept I program following three.
Now I am struck. How to to compile? I link all these file. I used following method:
Code:
gcc Sender.c -o Sender Sender.h
gcc Receiver.c -o Receiver Student.h
Then I run Sender and after that Receiver.I per my knowledge, Receiver should give difference but it gives error :
Code:

C++ :: Invoke Enum Class From Header File To Cpp File
May 21, 2014I have been working a project in C++. I have TTTMain.cpp file that has all the function calls, TTTFuntions.cpp that has all the functions, I have TTT.h file that has all the prototypes and variables and additionally I have Winner.h that has enum class Winner declaration in it. Here is my block of codes:
Winner.h file:
#ifndef winner
#define winner
enum class Winner {
[Code]....
My question is when I compile this gives me error on
Winner gameSquares[] = { Empty, Empty,Empty, Empty, Empty, Empty, Empty, Empty, Empty };
with saying "invalid use of non-static data data member" and It says "Empty was not declared in this scope."
I know calling enum is very very trick.
