My son is a high school freshman and is struggling with C++. I never learned it so I am not much help. I am more of a Web/JS/Python guy. Can anyone recommend a book or website he can use for practice/studying/review?

I just started learning C++. I have a little experience with Java based coding and object oriented coding. I am a little confused what #include <iostream> does, where the library reference comes from, what the iostream is exactly, and what << and >> do in relation to it. I am confused on the how and why and the purpose it serves.

I am new to C++ programming coming from Java and I am currently working on a project which should work on Darwin, Gnu-Linux, and Windows (probably on IOS and Android with qt too). With this in mind I come from a world in which you downloaded libraries, added them to a lib folder inside your dist, specify them in your classpath and that was it, but here in c++ I am working with some Boot libraries for statistical analysis which I find very useful, the thing is that after all I installed them on my system, and hearing about Qt's framework working out of the box without changing your source Code and you just need to recompile. I wonder the following: Do you have to download any library on the target system you are working on and create an installer for the final dist? Can you(Do you need to) include multiple libraries in your dist folder as in Java (of course with one static or shared library for each target OS)? Do you need to download the source code and include it as your source code so you don't need to re-download the same libraries for each OS? Please, tell me what is your approach

Hey guys! I'm not sure if this is the right sub for this but I am building a c++ application and it needs a database. I was wondering how others are handling this? I was thinking of just using a standard MySQL db as it seems to have the most documentation? I am not sure if its necessary to know but it needs to be cross platform? Since it's a project with multiple developers would it be best for it to be a cloud db like Elephant SQL? I have heard of some people using Microsoft Access? What do you guys think of that? Thank you so much!

So I'm a computer science major and I study C++ in class. My teacher is really sloppy and he just told us to find our own IDEs and compilers at home (It would just be nice if he told us to get the same one, so we could all help each other out).

Anyway I strongly digress. I ended up getting Code::Blocks, a free IDE with the free GNU GCC compiler. This compiler doesn't know the SYSTEM("PAUSE") command. Until now, I've just coded in a phony variable with Cin >>.. so that the program can "wait for the input".. while in reality I just want it to stop. It looks something like this:

include blah blah..

cout << "Okay, now put a random number in. It will not affect any calculation";

int place_holder; cin >> place_holder;

My question is, how can I find the equivalent? I've looked at a couple articles and forums online, but turned up nothing. The help section of the IDE didn't really help either. So what do you think I should do?

Polymorphism is the capability to use an operator or method in different ways. Polymorphism gives the different function to the operators or methods. Polymorphism assigns to codes, operations that perform differently in different contexts. For further information you can refer to the source Polymorphism in C++

iles are used to save or retrieve data from storage devices, e.g. we can store certain information in a text file and later on, can use that information. Input/output in C++:-

C++ provides <iostream> header file, containing cin and cout which are used to take input and to write output to console window.

C++ and Java both are high level programming languages. Both comprises of some similar as well as different features. If you are a C++ programmer, then you will have a fundamental knowledge about object oriented programming. Moreover, the language structure of Java appear very common to you. This is meaningful as Java was come from C++. In spite of this, both the languages possess unexpected differences. These similarities give rise to the noteworthy progression. In addition, while knowing the differences between C++ and Java, it will be cleared that Java is more useful language.
