As a coding language, C++ appeals to the ego, not the intellect

I discover that this web site has a tendency to extol the virtues of C++ as a programming language. As a person who has labored with C++ and who has adopted the debate close to its use for a long time, I believe it can be time to set the report straight.

The reality is that C++ is a single of the worst languages ever foisted on the marketplace. Considerably from remaining utilised in modern day buying and selling units, C++ must now only be used for legacy tasks. It is based mostly close to machine pondering, which is not programming pondering.

Generations of programmers have been misled by C and C++. Numerous have fallen into the black gap of its cult with trite platitudes like ‘under the hood programming’, which signifies no more than driving along with the hood open up, trying to resolve the motor, but unable to see the street. Cult followers urge stop-consumers to “rely on the programmer”, which is silly and naive, but appeals to the programmer’s ego. And programmers are intended to have “liberty,” even though no one ever suggests freedom from what.-  It can be absolutely not freedom from the flaws and traps of C++.

Programming is about programming and not about components equipment (applications run on theoretical machines). That appears really hard to recognize and counter to people’s intuition. C++ just supports the intuitive and populist considering rather of striving to correct it.

So not only is C++ technically lousy, but it is culturally terrible considering the fact that it appeals to the moi, somewhat than the intellect.

I am not the only 1 to dislike C++. Ken Thompson, the Bell Labs researcher who implemented the unique Unix operating technique, explained it as a “poor language” that is “way much too huge, way as well sophisticated” and “naturally created by a committee.” Damningly, Thompson also explained that C++ does, “a ton of things 50 % very well” but is “just a rubbish heap of ideas that are mutually exceptional.”

The trouble is that C++ is dependent on C and C itself is not a fantastic language. It is full of flaws and compromises. It compromised on compiler technological innovation, permanently forcing programmers to just take treatment of detail that ought to quickly be completed by a compiler. In turn, C was based on B, which was primarily based on Martin Richards’ BCPL, which alone was a minimize down on Christopher Strachey’s CPL, which was far too ambitions to be executed at the time. It is Strachey who is the actual genius in this article in my view, not people today like Bjarne Stroustrup, who now works for Morgan Stanley and who hacked OO into C to make C++, even although C wasn’t a very good base. 

Possibly way, if you are striving to learn C++ and you’re struggling to grasp it, it really is not you that is the challenge. The language is flawed. Developing a programming language is pretty hard, and C++ is basically not that effectively-designed. Systems programming and software programming are two quite different points, and C++’s serious concern is that it attempts to incorporate them both. 

Ian Joyner has completed quite a few matters, like market programming, devices programming, language and programming investigation and compiler progress, networking, dispersed system benchmarks and lecturing.
