classification of SD cards

There are mainly three sized SD cards
   

1. Macro SD card

       Micro SD card

                           These are medium in size and normally used in mobile phone.

         These cards are further divided into three types on the basis of size:

         These cards are also further divided into different class on the basis of speed:

   

• class 2
• class 4
• class 6
• class 8
• class 10
• UHS 1 ( Ultra High Speed One)

• UHS 2  ( Ultra High Speed Two)

• UHS 3   ( Ultra High Speed Three)

The class of  SD cards are written inside circle on the  card.This class represent the maximum speed  with which you can write data on the memory card.for example: class 2 means 2 Megabytes per second with which data can be stored on the memory.Now, UHS 1 and 3 support maximum speeds up to 320 megabytes.

     Mini SD card

                                These are smaller in size then other SD cards and they are not generally used in normal use.

SNAKE GAME IN C

Introduction:

If you want to develop snake game using C programming language then this blog obviously helps you.Hi i am Basant and i developed this game in my first year first semester project.

                                                             This is the project logo.

THERE IS CODE FOR THIS PROJECT WITH DOCUMENTATION:

Code:

Tools used:

• Dev-C++   IDE                                  (Dev-Cpp 5.11 TDM-GCC 4.9.2 Setup)  
• sublime text  text editor                      ( Sublime Text Build 3170 x64 Setup)

Discussion:

Finally i just want a say take only idea from this code it might show some error while running in your PC since it does not produce Byte code as produced by Java.
