INTRODUCTION TO "C" (PART2)-Hello World Program-A simple C program to display "Hello, World!" on the screen. Since, it's a very simple program, it is often used to illustrate the syntax of a programming language.Program to Display "Hello, World!"#include int main(){// printf() displays the string inside quotationprintf("Hello, World!");return 0;}How "Hello, World!" program works? The #include is a preprocessor command. This command tells compiler to include the contents of stdio.h (standard input and output) file in the program.The stdio.h file contains functions such as scanf() and print() to take input and display output respectively.If you use printf() function without writing #include , the program will not be compiled.The execution of a C program starts from the main() function.The printf() is a library function to send formatted output to the screen. In this program, the printf() displays Hello, World! text on the screen.The return 0; statement is the "Exit status" of the program. In simple terms, program ends with this statement.Data Types Associated With VariablesIn this section we are only going to discuss about the local variables. These are the variables that are used within the current program unit (or function). In later section we will have a look on global variables which are available for all program’s functions.There are five basic data types associated with variables:-1. int – integer: a whole number2. float – floating point value: i.e., a number with a fractional part.3. double – a double- precision floating point value.4. char – a single character.5. void - valueless special purpose type which we will examine in later sections.If you want to learn C programming, join C language course at ETL Labs, Gomti Nagar, Lucknow.

JAVA BASICS-INTRODUCTION TO JAVA-• JAVA is high level third generation programming language• JAVA is a Platform for application development• JAVA derives much of its character from C and C++• IDE’s for JAVA are : Notepad, Notepad++, Jcreator, TextPad, DosEditor, Eclipse.FEATURES OF JAVA- Simple- C++ Programmers can move to java will require less efforts  Secure- don’t instruct commands to the machine directly. Java program fully secured under the control of the JVM Robust -Platform Independent , Object Oriented , Programming Language, Memory management , Exception Handling Multithreaded - multiple task simultaneously Architecture-neutral - developed and executed anytime in future. No effect of changing environments like hardware, processor, Operating system.  Portable - ability to run the program on any platform and no dependency on the underlying hardware  Object-oriented - object oriented model in Java is simple and easy to extend Interpreted - JVM interprets the ByteCode into Machine instructions during runtime. High performance - interpret only the piece of the code that is required to execute and untouch the rest of the code Distributed - Remote Method Invocation (RMI) using which a program can invoke method of another program across a network and get the output. Dynamic - update the pieces of libraries without affecting the code using it We are starting a new Batch of Java from this week.
