Iterating over a range of User Defined objects and calling member function using std::for_each
In this article we will discuss how to iterate over a container of user defined objects and call a member function on each of the iterating element.Suppose you have a vector of Employee class objects and you want to call a member function on each of the element in vector. [showads ad=inside_post] Let’s see how …
Using std::initializer_list in constructors to initialize member variables
In this article we will discuss how to use std::initializer_list<T> to initialize member variables. Suppose we have a class Point that has 3 member variables representing x, y & Z axis coordinates. It has a parameterized constructor too i.e. Advertisements class Point { int mX; int mY; int mZ; public: Point(int a, int b, int …

C++ : How to pass class member function to pthread_create() ?
POSIX Library provides a function pthread_create() to create threads i.e. #include <pthread.h> int pthread_create(pthread_t *thread, const pthread_attr_t *attr, void *(*start_routine) (void *), void *arg); It accepts a function pointer as startup routine. This function accepts void * as argument and returns void *. In previous article we discussed how to use this API with global functions …

C++11 Lambda : How to capture member variables inside Lambda function
In this article we will discuss how to capture member variables from outer scope. Suppose we have a class OddCounter to keep the track of odd numbers read by the object. Inside its member function we are creating a lambda function and passing to a STL algorithm std::for_each. Advertisements Now this lambda function needs to capture …

C++11 : How to use std::thread as a member variable in class ?
In this article we will discuss how to use std::thread object as member variable inside class and its benefits. As std::thread objects are move only, therefore while designing a class that use std::thread as member variable, we need to take care that objects of this class should also be move only. Advertisements Creating Move-only class with …
