Scenario as below:
I have two module, A and B
Module A:
- A.cpp & A.h
Module B:
- B.cpp & B.h
and then for these two *.h file i put in another centralized folder call HeaderFile.
when I #include "B.h" from A.cpp, the compiler show me Error code C1083.
How do i go around the code for this screensaver..

I tried some examples from other people's code but it doesn't seem to work. Tried to ask the owner aswell but it doesn't seem that he would be able to reply as he's been inactive.
I'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
I need a code in c++ . It should count the Files and Directories in root folder with every folder information i need the below information
1) no of files and folder
2) how many files are there in each folder
3) with size of every folder and files it contains

I want to make a launcher for my program but the installation folder is different from one computer to another so I need a function or something that shows the path of the executable file.how to import a file from another folder.
#include<stdio.h>
int main(void)
{
FILE *fp;
*fp=fopen("C:Documents and Settings...something.txt","r");
}
You see I want to set the import path.
i get the name of file upon every OK click in the list of array.
i want the file name to be written in command prompt to install the file like
C:WindowsSystem32msiexec.exe filename.exe /quiet
fi is array representing the files
following is a code ..
foreach (FileInfo fiTemp in fi)
{
p2.StandardInput.Write("msiexec.exe ");
p2.StandardInput.Write(fiTemp.Name);
MessageBox.Show(fiTemp.Name);
}
Say, I have the "K: est del USB" folder.
Then I do the following:
Code:
SHFILEOPSTRUCT sfo = {0};
sfo.wFunc = FO_DELETE;
sfo.pFrom = L"K: est del USB";
sfo.fFlags = FOF_ALLOWUNDO |
[Code] ....
So when I run it, the SHFileOperation API shows this warning:
Are you sure you want to permanently delete this folder?
If the end-user clicks "No", SHFileOperation return 0x4c7, which I believe is ERROR_CANCELLED.
My question is, if I don't need any UI, how can I know that my file/folder will be permanently deleted vs. placed into the Recycle Bin?
I'm writing a small function that gets as parameter a file's path and a folder's path, and copies the given file to that folder.
Code:
int copy_file(const char* source, const char* folder) {
char copy[PATH_MAX];
strcpy(copy, folder);
strcat(copy, "/");
strcat(copy, source);
[Code] ....
Basically, this function purpose is to make a backup of source in folder every X minutes (depending on user's input).
The problem is the second call to open():
This call attempts to open the file for writing, and creates it if it is not already exist.
It also truncates it before writing to it - and that's my concern:
Let's say this is the second time this function runs, so copy is already exist. open() will then truncate it, and then one of the system calls in the while loop fails.
In this situation, I might be left with no backup file.
The problem also arises for when source is a read-only file:
If source is a read-only file, and copy is not already exist (meaning - it's the first backup attempt), then everything's fine, but, if source is a read-only file and copy is already exist, then I have to first remove copy altogather, and make a fresh copy of source.
Making a backup with new name for copy every time copy_file() runs, will solve this problem, and how can this be accomplished?
I should say that I'd really prefer that copy and source will have the same names when copy_file() returns...

I 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?

What 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.
lets 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.
I 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:
Receiver.c: In function "main":
Receiver.c:10:42: error: "Send" undeclared (first use in this function)
printf(" Total Receive is %d
",Receive-Send);
Code:
Sender.c

I 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.
I am beginner in c++ language. i'm use visual studio 2010 ultimate. the problem is i can't add c++ file(.cpp) and header file(.h).

I made my header file. If cpp file with definitions is in project compiler knows it has to be linked, but if it's not compiler doesn't know. If I include standard library or boost I don't have to manually link cpps. How to do so including my header automatically links cpp? Maybe problem is with something else?I use VS 2013.
