Hello World!

Jan 27

As I write the first Keyes Security blog post entry, it is only fitting (as a developer and security professional) to kick things off by saying “Hello World” and discussing the origins of “Hello World” programs.

Brian Kernighan is the person who first used “hello  world” program as part of the BCPL programming language which was developed by Martin Richards. Brian Kernighan wrote the code for part of the I/O section of the BCPL manual. This is confirmed by Martin Richards himself, who can still be contacted at Cambridge. This 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. Later to become a standard for new programmers.

All the Best,
