Samsung Smart TV Apps – Hello World

First post of Samsung Smart TV SDK 3.0.0 and definitely it's a Hello World application :D

If you're doesn't have a Samsung Smart TV SDK just go to www.samsungdforum.com and register there, it's totally free and you can download the SDK in "DEV TOOLS" menu. Installing the SDK is little bit something in Windows 64-bit, some people in forum said that they are facing problems when installing it but my installation in Windows 7 Home Premium 64-bit is done very well.

Counting Size of Struct in C

First, i didn't guarantee that this post will give a true answer for any problem because this conclusion just made by myself based on my observation on some codes. It's very welcome to give another opinions or answers to share more knowledge and better solution.

This post will discuss about how much a struct take a memory? because of structs is a user-defined data structures, it's size will be relative to the content that the struct stores. For beginning let's refresh our memory (brain) about two most-used primitive data types size.

int (4 bytes / 32 bits)
char (1 bytes / 8 bits)
