Wannna know more about "Hello World" !

Well well well......Mayank i think i can answer ur query now ........u asked me as to why do we use " Hello World " as ur 1st program...
Here it goes............

While small test programs existed since the development of programmable computers, the tradition of using the phrase "Hello world!" as the test message was influenced by an example program in the book The C Programming Language, by Brian Kernighan and Dennis Ritchie, published in 1978. The example program from that book prints "hello, world" (i.e., no capital letters, no exclamation sign; those have entered the tradition later). The book had inherited the program from a 1974 Bell Laboratories internal memorandum by Kernighan —Programming in C: A Tutorial— which shows the first known version of the program:
main( )
{
printf("hello, world");
}
However, the first known instance of the usage of the words "hello" and "world" together in computer literature is in A Tutorial Introduction to the Language B, by Brian Kernighan, 1973.
Environments that generate an unreasonably large executable for this trivial test or which require a hairy compiler-linker invocation to generate it are considered to lose

The basic belief was that learning a language meant more than learning grammar and vocabulary, syntax and substitution drills. They believed it includes an intense understanding and respect for culture and diversity.
