Basic Knowledge Of C language: >C is programming language. Compiler is developed by Dennis Ritchie in 1972 on PDP-11 unix based system. >C is high level language. is case sensitive language. >Standards of C Compiler ---- C89, C99(lastest standard) >in c89 32 keywords are available. >in c99 32+5 keywords are available. >C procedural language. >Data types :     *Primitiave data types:         -char,int,float,double     *Derived Data Types           -structure,union,array,pointer > Type modifiers: long,short,signed,unsigned    > Identifier rules :             1.We can not add space,any special character                   2.

Aptitude Exam Software For Linux using GTK2+ : I developed this software on openSuse using gtk2+ paython. we have case competition for moc recruitment in our institute so we choose KPIT compancy . for conduct aptitude exam i develope this software.  Requerment: > OS :linux (any) > Library : gtk2+ requered  > for testing purpose LAN connection or you can use Loop Back adress(ie 127.0.0.1) > knowledge of inet socket screen shots given below USER NAME :  <any text> U-ID : KPIT-<any text> Server Side: step 1 :  change IP address and port in files "allheader.h" step 2 :   compile server aplication using gcc compiler $ gcc -c main.c $ gcc -o main main.o $ ./main step3: first start server then exam application. here i given screen shot of server side applicatio and client side application left side having list of exam submitted students and right side the sorted list according to marks. step 4: application side screensh

Project titled "Clap Operated home Appliances" It is known as Clap Switch , because the condenser mic which will be used in this Project will have an ability to take the sound having same pitch as the Clap sound as the input. Although it doesn’t mean that the sound will have to be of Clap sound, it can be any sound having the same high pitch as of Clap. We can also say that it converts the Sound energy into the Electrical Energy, because we are giving an input to the circuit as a sound whereas the Circuit gives us the output given to 12v relay to drive 230v powered devices. This is my third year project of engineering . in which i used 8051 micro controller( 89v51rd2 as it is easily programmable using rs232 protocol ). In this project the sensor circuit uses low power op-amp IC LM324 and simple microphone taken out from mobile headphones. fig: Circuit diagram is as given below Download link for Source code : Download Source Code
