C++ for C and Java programmers: 1 hour learning is possible?

fortea · 08-26-2014, 05:21 PM

Hi all! I'm a nearly new user in this forum.

I have a question for experienced programmers: I know pretty good java and c languages. I also made some simple programs in C ++, but now I would like to learn well C++

Does anyone know some free online document dedicated to java AND c programmers?

Thank you very much!

There's a sticky thread for free C++ tutorials at the top of this forum.

I don't think any of them are aimed specifically at C or Java programmers, but both languages are similar enough to C++ that you'll have an advantage.

And no, it's not possible to learn C++ "well" in only one hour.

That depends on what you mean by "well". An experienced C/Java programmer should be able to learn to write some C++ code within an hour.

ETA Oops! I see the OP already got that far.

Yes, I saw them, but I was looking for a manual dedicated to Java and C programmers. Maybe I can read a program of small-medium size (500-1000 as lines of code), where I can find all the key features of C ++? Any suggestions?

So you say you know java. Do you know all the available libraries for java (like swing, awt, corba, whatever...)? Knowing c++ means not only be familiar with the syntax but using templates, compilers, using libraries (and their features) and so on (debugging ....). Of course you can learn 1 hour, but that will not be sufficient....

Basically, the answer is: "No."

In an hour, you can learn enough about a hammer to smash your fingers with it ... but not too much more. And, you should already know this from your experience with Java. Could someone who "knew C++" learn as much as you know about Java ... about building sturdy real-world applications to address real-world problems for businesses ... in an hour? You know the answer is "no," because you know implicitly how much "besides the syntax of the language" that you know about Java from years spent working with it.

Ok, it's clear that I cannot become a master of C++ in one hour. The thing I want is to learn the essential so that I can begin to program. For example: I don't need to learn all C++ libraries or all Java libraries; today it is absurd to learn all libraries available, it is really more simpler to learn step-by-step when you need something new (yes, internet is a wonderful resource for this!).
And for the compiler... not now: just essential for my pc, no optimization.
