Which demonstrates that you have indeed written, compiled, and executed a program in the C language.Īs Kernighan and Ritchie note, building the program for C means that you’ve mastered the basic steps to start a C project. Type that text into a file named ‘hello.c’, then (on any UNIX-like system) enter the commands $ cc hello.cĪnd you should see the cheery result Hello, world! The first program most C programmers write is something like: #include Ritchie’s The C Programming Language (First Edition)- writing a small program in order to confirm that you understand the language and environment enough to try more complicated things. This notion of a “Hello, World” program goes back to Brian Kernighan and Dennis M. The client’s program was relatively simple, but I didn’t want to just dive in. Building the program required me to remember how to use a KEDIT-like editor, learn how to use the AS/400 Software Development Facility, build a testing library, edit the actual program, then compile it and figure out how to run it. I don’t want to admit how long it had been since I last wrote RPG other than to note it was probably before most of my readers were born. To quote the Great Lobachevsky, “боже мой!” You may edit this file according to your requirement.Not too long ago, a client called on me to write a program in RPG on an AS/400.
