The statement as written compared x to 2, generated true or false, and discarded the result. The programmer 's finger had bounced on the "equals" key, accidentally pressing it twice instead of once. X=2 It was a typo for what was intended to be an assignment statement. After some intensive debugging sessions, the problem was finally traced to a statement that read : The bug was holding up the sale of $20 million worth of hardware to a customer who specifically needed the library functionality, so we were extremely motivated to find it. The $20 Million Bug In Spring 1993, in the Operating System development group at SunSoft, we had a "priority one" bug report come in describing a problem in the asynchronous I/O library. Then, if an equal sign is accidentally left out, the compiler will complain about an "attempted assignment to literal." This won't protect you when comparing two variables, but every little bit helps. Some programmers have developed the habit of writing the literal first, like this: if (3=i). If (i=3) Once experienced, this painful error (doing an assignment where comparison was intended) is rarely repeated. Almost every beginning C programmer independently rediscovers the mistake of writing: These are acquired slowly over time, learned from looking over the shoulders of more experienced colleagues, either directly or while maintaining code written by others. Expert programmers build up a tool kit of techniques over the years a grab-bag of idioms, code fragments, and deft skills. ![]() It is intended for people who are already writing C programs, and who want to quickly pick up some of the insights and techniques of experts. This book is an advanced text on the ANSI C programming language. In natural language terms, this is the difference between being able to order a cup of coffee in Paris, and (on the Metro) being able to tell a native Parisienne where to get off. But it takes much longer to master the nuances of the language and to write enough programs, and enough different programs, to become an expert. ![]() A reasonably sharp person can learn the basics of C quite quickly. Peter Weinberger Have you ever noticed that there are plenty of C books with suggestive names like C Traps and Pitfalls, or The C Puzzle Book, or Obfuscated C and Other Mysteries, but other programming languages don't have books like that? There's a very good reason for this! C programming is a craft that takes years to perfect. Run code run…please! -Barbara Ling All C programs do the same thing: look at a character and do nothing with it.
