We decided to write several small posts on how C/C++ programmers play with fire without knowing it. The first post will be devoted to an attempt to explicitly call a constructor.

Programmers are lazy creatures. That's why they tend to solve a task using minimal code amount. This aim is praiseworthy and good. But the main point is not get too involved in the process and stop at the right time.

For example, programmers are too lazy to create a single initialization function in a class so that it could be called from various constructors later. They think: "What for do I need an extra function? I'd rather call one constructor from the other". Unfortunately, sometimes programmers can't solve even such a... [Read More]

WordPress out of the box is pretty secure still if you follow few simple security tips and install few security plugins, it can make your Wordpress lot more secure.

What is Dameon Process?

A Daemon process is a process which is not associated with any terminal and hence is supposed to run in background. Since, a daemon process involves background processing, it is recommended it should not include any user interaction. Therefore, it should be clear about its continuous processing not caring to wait for any input or to display any output. However, C programming does not define any such restrictions in its development as such. A daemon process developer should be well aware of its definition and ideal functionality before one starts the programming.

A well known example of a daemon process could be a mail server, which runs... [Read More]

In C-Style typecasting we discussed about type casting and why is it required and how it is used in C programming. C++ has more types of typecasting and an entirely different way to use them.

A point to be noted that C++ typecasting would be mostly described and used in context of classes, as an effect of C++ being object oriented.

Types of C++ TypeCasting

There are following four types of type casting in C++:

Static-cast

Static cast is generally said to be used for... [Read More]

This article is the Part-II (Part-I here) of the series where in we are focusing on good coding practices. In the Part-I we discussed the importance of the assert macro/function for detecting and debugging bugs in program. In this part we will focus on good coding practices while dealing with system calls.

Note: As always, we will be discussing everything in the Linux environment.

Working with system calls

There are certain points that one should keep in mind while dealing with system calls.

• One should have in and out knowledge of the
