(Related to C++0x, How do I expand a tuple into variadic template function arguments?.) The following code (see below) is taken from this discussion. The objective is to apply a function to a tuple. I simplified the template parameters and modified the code to allow for a return value of generic type. While the original code compiles...
It's said Symbian C++ has its own dialect, can someone list the exact aspect that differs? ...
Hello, everyone! In a project I'm working on, I have a Score class, defined below in score.h. I am trying to overload it so, when a << operation is performed on it, _points + " " + _name is returned. Here's what I tried to do: ostream & Score::operator<< (ostream & os, Score right) { os << right.getPoints() << " " << right.scoreGetN...
We would like to create some simple automated tests that will be created and maintained by testers. Right now we have a tester who can code in any language, but in the future we might want any tester with a limited knowledge of programming to be able to add or modify the tests. What is a good programming language for testers who are not...
Time was when you set file associations in: HEY_CLASSES_ROOT\<.ext> However, that seems to be possible, but an incomplete solution anymore. There are additional associations throughout the registry. For example: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\KindMap HKEY_LOCAL_MACHINE\Software\Microsoft\Window...
#include<stdio.h> void print(int *arr[], int s1, int s2) { int i, j; for(i = 0; i<s1; i++) for(j = 0; j<s2; j++) printf("%d, ", *((arr+i)+j)); } int main() { int a[4][4] = {{0}}; print(a,4,4); } This works in C, but not in C++. error: cannot convert `int (*)[4]' to `int**' for argument `1' to `vo...
I'm getting these two warnings (with GCC 4.2 on MacOSX): /Users/az/Programmierung/openlierox/build/Xcode/../../src/main.cpp:154:0 /Users/az/Programmierung/openlierox/build/Xcode/../../src/main.cpp:154: warning: 'startMainLockDetector()::MainLockDetector' declared with greater visibility than the type of its field 'startMainLockDetector(...
Hello everyone. I edited a post of mine with this question, yet got no answers. I overloaded << for a class, Score (defined in score.h), in score.cpp. ostream& operator<< (ostream & os, const Score & right) { os << right.getPoints() << " " << right.scoreGetName(); return os; } (getPoints fetches an int attribute, getName a string ...
I am trying to specialize a metafunction upon a type that has a function pointer as one of its parameters. The code compiles just fine but it will simply not match the type. #include <iostream> #include <boost/mpl/bool.hpp> #include <boost/mpl/identity.hpp> template < typename CONT, typename NAME, typename TYPE, TYPE (CONT::*getter)()...
What is purpose of this keyword. Doesn't the methods in a class have access to other peer members in the same class ? What is the need to call a this to call peer methods inside a class? ...
Can anyone tell what's going on here? When I try debug the code and when the control is in thread() function at Line 15, it skips over the Line 16 move to Line 17 and goes back Line 16. Why wouldn't it move Line by Line? 1. #include <boost/thread.hpp> 2. #include <iostream> 3. 4. void wait(int seconds) 5. { 6. boost::this_thread::...
hello. A little bit of background: I have some strange multiple nested loops which I converted to flat work queue (basically collapse single index loops to single multi-index loop). right now each loop is hand coded. I am trying to generalized approach to work with any bounds using lambda expressions: For example: // RANGE(i,I,N) is ...
void* GetData() { return reinterpret_cast<unsigned char*>(this); } Is there a case of automatic type coercion happening in this case ??? How could I convert the object of my class to an unsigned char* ?? ...
So i am upgrading our service to go to the new OAuth security measures. Using a single twitter account to send Direct Messages to users for an alert. I wrote up a quick app that retrieved the access token and secret using the Java library. But the kicker is that i need to send these messages via C++. and a Javascript file. (this is curre...

I'd like get far next value for STL list iterator but it doesn't implement operator+, vector has it though. Why and how can I get the value where I want? I think I can do that if I call operator++ several times, but isn't that a little bit dirty? What I want to do is the following: list<int> l; ...omitted... list<int>::iterator itr = ...
I'm using RHEL 5.3, shipped with gcc 4.1.2 and boost 1.33. So, there's no boost::unorded_map, no make_shared() factory function to create boost::shared_ptr and other features available in newer releases of boost. Is there're a newer version of boost compatible with the version of gcc? If yes, how the upgrade is performed? ...
When you want to inherit from a class in C++, is it illegal to have std declared in the first line below? #ifndef HWEXCEPTION_H #define HWEXCEPTION_H #include <stdexcept> class HWException : public std::run_time_error { void testException(int num); }; #endif vs using std::run_time_error class MyClass : public run_time_error ...
