C++11 - Uniform initialization

C++11 standard provides new form of objects initialization which makes such initialization uniform for different structs and classes and simplify objects construction and initialization process. Thanks to the new process we can initialize many different classes using the same syntax.

Please take a look on the example below: Output of this example is: In point I we are initializing class of two different objects using C++11 uniform initialization mechanism. On object is created based on struct type (pure struct type without any method - look point II). The second one is created based on MyClass class constructor.

As you can see, despite that we are creating objects of two totally different types, those objects can be created the same way (uniform way). This is just uniform unitialization featuere provided in C++11 standard.

Below we are initializating MyStruct object using external function getMyStruct(). You can take a look to the body of that function (point IV). As you can see we are implicitly using uniform initialization form of struct MyStruct inside getMyStruct() function to create object.

However you need to be careful with using uniform initialization for classes having initializer_list constructor. In such case, initializer list constructor has higher priority than uniform initialization and constructor will be used instead of uniform initialization. So be aware of it and enjoy your C++11 programming :)

Advanced C++ - Mutable Class Field

Today I would like to present C++ class' feature called mutable class field . Mutable class field is class' field modifier which allows to change its value even if object of the class is declared as const . Take a look at the example: Output of this example is: In point I of that example we are defining object of TestClass . Note that this object is const . As you can see in point Ia this class has three different member fields ( constInt, mutableConstInt, nonConstInt ). Those variables are public for this example, but do not worry about encapsulation here. It is just omitted for simplify this example. As you can see one of this member fields is marked as mutable class file using mutable keyword ( mutableConstInt ). Such variable can be modified even if object of class TestClass is const . It will be explained in next points of this example. In point II we are printing default values of testObject object initialized in initialization list of TestClass' default c...

C++ Multithreading - Race conditions

In the previous C++ Multithreading article I presented you how to pass parameters between threads. Take a detail look on the output of that example once again: In the first line of that output you can notice that output text from two threads is mixed. You are probably wondering why it happens? It is because we are not protecting resources which are shared by two threads (in this example cout stream is shared in both threads) which causes multithreading's phenomenon called race condition . Because threads switching and accessing to shared resources are managed by operating system we do not know when std::cout stream will be accessed by main thread and when it will be accessed by second thread. Therefore in the previous article I mentioned that output of the example can be little different on your computer than my output example. What's more it is possible that this output will be different for few consecutive invoking of the example on the same machine. It is beca...

C++14 - Tuple addressing via type

Today I would like to introduce one of new features which will arrive to C++ with new language standard (C++14) which is going to be release in 2014. In order to compile example from this article you need to have compiler supporting C++14 standard. The newest version of GCC supports it. I would like to introduce you features called Tuple addressing via type which allows us to get tuple element value using type name instead of tuple parameter number. Of course it is possible only for type names which are not ambiguous. Let's take a look on below example for better understanding: In point I we are declaring our tuple type containng of 2 int elements and on string element. In point II we are using std::get function to get values of our tuple typed variable using tuple parameters numbers. This feature is well known from C++11 standard. Point III shows new (introduced in C++14 standard) way of getting values of tuple elements. We are getting string type element using...
