I have also thought why do we have this “Hello World” Program every time we start with a new language. Being the first blog too I thought what better than this?
So here was what i found out, the reason for “Hello World”
Brian Kernighan actually wrote the first “hello, world” program as part of the documentation for the BCPL programming language developed by Martin Richards. BCPL was used while C was being developed at Bell Labs a few years before the publication of Kernighan and Ritchie’s C book in 1972.
The first documented use of code to print the message “Hello, World!” Brian Kernighan remembered writing the code for part of the I/O section of the BCPL manual. Martin Richards — who seems to have a treasure trove of notes, old documents, etc. — found the manual and confirmed that the this was the original appearance of the program. The code was used for early testing of the C compiler and made its way into Kernighan and Ritchie’s book. Later, it was one of the first programs used to test Bjarne Stroustrup’s C++ compiler.
It became a standard for new programmers after it appeared in Kernighan and Ritchie, which is probably the best selling introduction to programming of all time.
