Are there reasons for beginner programmers to learn C ?
-
I'm always flabbergasted when I ask basic questions about using an object that implements IDisposable to developers with many years of C# experience and they are completely clueless, let alone the caveats about implementing it correctly. It's even rarer for developers to know about the using statement. I often wonder how their apps don't leak database connections all over the place. I worked with one system that completely threw me for a loop. Every object was created in a using block in a factory method and returned to the caller. Each object was auto generated with a sql connection as a property which was opened in the constructor. Calling dispose closed the connection so it could be returned to the "business logic" layer. :sigh: :doh:

What you are describing there has nothing to do with having C# as a first language... Actually it has nothing to do with programming! It sounds more like these people were baking an apple pie and somehow ended up in an office with a computer where someone mistook them for programmers.

I can't imagine how that would've been... Employee: "There's a bug in Visual Studio that throws ObjectDisposedExceptions at random!" Boss: "We better turn off the 'Break when a common language runtime exception is thrown'-option then!" Third person: "Perhaps there really IS something wrong in your software?" Employee: "Hell no! I'm even using the 'using' keyword with some Objects that can, for no appearent reason, be used with it. Microsoft recommends it!" Boss: "Good job, now we should send Microsoft a report on that Visual Studio bug..." Third person: "By the way, I'm out of apples, anyone here has some?" Employee: "Sure, if I can have an ounce of flour." ... :laugh:

Language feature should make our lives easier to make portability as transparent as possible. Using standard C++ libraries (streams, collections, algorithms, memory management, ...) ), I can write portable code that runs on major OS without the need to think about it.

If you're writing generic algorithms, of course. Writing a high performance server or something comparable and it's a different situation. The standard C++ libraries make up a miniscule fraction of the code base I'm working on (and some of that is still tricky, such as the differences in UNICODE. A few days ago, I had a small class where the entire class is different between Win32 and Linux. Another class has huge differences between Win32 and CE; I haven't even looked at what the Linux version will be like. :) )

I somewhat agree, but I would chose those languages only for lower level of education.If it's for college than I am for C all the way. What the heck, C should be in secondary schools as well.

Exactly.

Yes, after they have the fundamentals and before they're released on the world.

That's debatable. I'm taking a class that brings you from NAND gates and D Flip Flops all the way up to the operating system (so far I've built a computer (CPU + RAM) from only NAND and DFFs and an assembler), and I don't see much relation to C. Admittedly it's a better model than a higher level language like C# or Java, but it's still pretty far abstracted.

I call that an FPGA course. I was more talking about Microcontroller "computers" from the ground up with C. using the chipset data sheet to write a HAL from register addresses etc etc etc.

Are there reasons for beginner programmers to be taught C instead of C++? I'm not even thinking about Object Oriented programming, but simple declarative programming. I'm reading a lot of questions on CodeProject and on StackOverflow where people ask about issues with C language features that are so prone to errors and defect that it makes me cringe. A lot of those issues could be handled by simple C++ features (memory management (new/delete, smart pointers), strings, collections, references, ... ) I know there are lot of legacy code out there and it should still be maintained, but old code "ways" should not be the emphasis of the education. :confused:

It may produce a spiritual awaking. C was deliberately written to be unrestricted (to port the Unix O/S). It does what it's told to do, no questions asked. That means you have to pay attention to what you're doing. That is a good habit to learn. I'd even go so far as to suggest you dabble with the in-line assembler.

I have found that that you have to pay attention to what you do in any language, otherwise you get into spagetti. It is understanding the concepts of OOD, events, design patterns, architecture that is difficult because you have to wrap your mind arround them. Basic programming should be a one semester course, and then move on to real issues in application programming.

Well, I don't care (one example of many) how std::string internally manages the string, I just want to do
std::string s("hello world");. it is safe, it is efficient.Watched code never compiles.
Maximilien wrote:

std::stringis not efficient if you're not using it properly and according how it manages string internally,Maximilien wrote:
it is safe
and
std::shared_ptris not safe if you're using it incorrectly (circular references). So if you really want safe and efficient code you need to know how those high-level concept works on a low-level. -

In my opinion, a lot of people really need to better understand how to use correctly C++ in an object-oriented way. When people first learn C, then often only use C++ as a better C... In my opinion, if someone learn C++ and also read Meyers book, he will know the essential. The main advantage of knowing C might be for some embedded development where C++ compiler are not available.

I started with VB5 in grade8. Then study C++, Assembly, Java in University. And Start my first work with RPG4, CL and LANSA. But Now I'm working on VB.NET Even if I'm not a good programmer. For me Programming Language is just a tool. I think which language to start doesn't matter.

Not as a first language. Nor should an OOP-only language (VB, C#, etc.) be the first language. In my opinion BASIC and Pascal (and maybe Perl?) are still good first languages even though they won't apply very well to modern business. Professional developers still to be smacked with C.
When I first started out, I did learn Pascal. Then moved onto C. Then Perl. Then C++. Start off with Perl? No because there are those strange UNIX syntax. To keep it clean, Pascal but yes I don't think it has much real use in business. Start off with C? I think that is ok.

Yes - C is simpler and a much smaller language than C++. C is great for learning about functions, pointers, memory management and calling operating system libraries. C is a beautiful language that allows you to program efficient algorithms. You can learn about how different data types are stored and represented in memory. C will give you the power to implement classic computer science structures and algorithms: arrays, trees, sorting and linked lists. If you 'get' C, you will know that you have what it takes to be a real programmer. C will give you small, lightweight and fast executables. With C, you will have a very good foundation that will complement what you learn with other higher level languages; and the lower level assembly language. Once you know C, it will stand apart from all other languages that you learn.

If the idea of a high-level programming language is to hide hardware details from the programmer, there should never have been any commands associated with memory management in the language.

" There is a difference. Now, if you were wanting to learn about programming, I would not recommend C as a starting point. However if you were being taught programming as part of, say, a course in microprocessor systems engineering then C and assembler would be highly appropriate.

I think learning C (and maybe also assembler) is a very good way to understand what really happens. Personally, I find it quite painful to program in these languages, as I prefer a higher order of thinking that does not distract me from doing algorithms and a good software design. But to understand what really happens and why XY now behaves just the way it does, I find it very useful that I have learned ANSI C and i386 Assembler.
