About C++ Programming:-
C++ is a general-purpose programming language that was designed to incorporate object-oriented concepts as an improvement of the C language. It’s a compiled language and an imperative language. If you are new to language you will get initial question that How long does it take to learn c++ ?
C++ is a high-level language that gives it the advantage of low-level programming (drivers, kernels) and even higher-level applications (games, GUI, desktop applications, etc.). Both C and C++ have the same basic syntax and code structure.
- High – level programming Language :-
C++ allows seven different programming types or more. Developers can pick any of those models.
- General Purpose Language :-
C++ can be used to build games, desktop applications, operating systems, etc.
- Speed :-
The efficiency of optimized C++ code is exceptional as with C programming.
- Object-oriented :-
C++ allows the use of objects to break complex problems into smaller sets.
Why do I learn C++?
- Because of its output, C++ is used to build games, desktop applications, operating systems, browsers etc.
- After learning C++, learning other programming languages such as Java, Python, etc. would be much simpler.
- C++ allows you to know a computer’s internal architecture, how the computer stores information and retrieves it.
How to learn C++?
Every computer programmer has to be a superior programmer, but not everyone is successful.
If you are already programming in other languages, this question you would definitely not be asked. So rather than answering your original question, I’ll give you some useful advice. Learn the fundamentals of software engineering instead of focusing on C++.
C++ is only one of a variety of languages used for software programming. But if you don’t understand data structures and algorithms, you’ll probably get confused when you start using C++ (or any other programming language of that matter).
Can I learn C++ fast?
If you know the language of C then it will be very simple. And do a lot of little programs to train you well and to understand all the concepts of objects and the source language.
If you don’t know C so it’s going to take longer. Just read book about understanding the definition and reading the source code.
How long it takes to learn C++?
Its depend on you if you know any other programming languages like java and Python.
Learning the basics of C++ would not take a long time, it will take 2/3 weeks, While Learning C++ will take you that long if you concentrate only on functional C++ such as input and output, excluding objects, classes, and file operations.

Best way to learn c++
The best way to learn C++ is, to write lot of code in C++. This is also true of any and every language in the programming.
That said, however, out of all mainstream programming languages C++ is possibly the least beginner-friendly. It takes a long time to build a strong mental model of C++, due to its complexity. Here is an example of that. The next program in C prints “Hello, world!” implemented by a newline:
I ‘m sure someone has clarified that “\n” is a special sequence meaning “new line.” So later you could write this when you read about string variables.
(Probably anybody explained that ‘%’ means ‘printing the contents of the string variable’)
Now let’s go for C++ .
Someone says that this prints “Hello, world!” and a newline follows. So later you’ll hear about C++ strings, and you’ll try:
Can you think what? This is not compilation. And the message to error says,
For fully understand the processes of the original software, you need to know that std::endl is not a newline character at all. To really comprehend how std::endl functions is beyond beginners’ comprehension.
- A good teacher can’t do much more than tell you std::endl at this point is something which only makes sense when you send it to a line.
- A bad teacher would be too spineless to know themselves that std::endl isn’t a newline character, and they’ll tell you that it is, and you’ll be hopelessly confused.
But even in the first case you’ve just learned an arbitrary-seeming law, with no conceptual model for how it functions. If you know the language very well, a lot of things just won’t make sense.
C++ isn’t beginner – friendly. But if you read a book about C++ you have a better chance. There is a issue here again. C++ is so complex that not even the majority of C++ programmers understand the language well.
You ‘re going to have problems down the way. Often, in C++, you really don’t know how to do something. Now you’ve got two choices. You can come and post a query here, or maybe on Stack Overflow, or you can just check for a code snippet that will do what you want, and paste it into your software and change it until it works.
You’ll have written thousands of lines of C++ code after months, or maybe years, and you usually get a clear idea of how C++ functions in most cases. But frustratingly the words can still make no sense. Occasionally you could get error messages that are long whole pages. You would really like to grasp the nitty-gritty of C++ at this stage.
What do you do ?
Reading more of such books! See the “Intermediate” and “Advanced” parts of both connected to it.
“The creation and development of C++” is also a worthwhile read by the developer of the language himself. And tackle bigger tasks, encouraging you to use even more pieces of the vocabulary. I wrote over 80,000 lines of C++ code over a seven-year period. I’ve written more than twice as much C++ code as I have put together in all other languages. But I also want to know more on C++. I want to know what there is to know about C++.
If you know C how long does it take to learn c++?
Usually, C is a subset of C++, C++ is basically C with some additional features and concepts such as the framework for the object. All in C, then, is true in C++. Some declarations are going to be a little different. In C++, arrangements, unions and all these C personnel can be modified a bit. In general, it won’t take long to learn a C-Style language if you know any of it about C or C++. Already learning C, you essentially know the toughest sections of C++ (as seen from C++ scoffers’ point of view, saying it’s difficult).
Moving From C to C++
Moving from C to C++ is simply going from procedural programming to programming of objects(OOPS). It is all about improving the way you think about how you look at a programming problem.
You would be learn the basics of the OOPS and start identifying entities and relationships but when you start writing any code.
A Class can represent an entity, and it is an Object. You build a “is a relationship” between your Derived class and the Base class when you inherit from a Family.
For that so you have to learn the following concepts.
- Object Oriented Programming.
- Basic Syntax of Object Oriented Programming.
- C++ basic Syntax and Standard Library.
If you know java how long does it take to learn c++?
I can say, since you already know Java, that you are familiar with the programming basics.
You’ll need to learn how to control the memories. Java does everything you need to handle memory, but C++ does not. This is very critical because dynamic allocation without deletion can lead to leaks in memory.
I recommend you start studying simple syntax before you get to the more complicated subjects like templates and different techniques of optimization, because studying too much at once will confuse you and make it difficult to write good code. Writing small tasks and playing with new features you learn is a good way to learn, and over time you’ll learn how to use more advanced features.
I started with Java but I got really caught up with the idea of pointers when I tried to learn C++. It turns out, all the time, Java uses pointers — they ‘re just called Java references. The key difference I see with C++ is that you are not required to allocate every object on the heap (using new ones), just like every standard primitive you can allocate them on the stack.
There are a lot in common between C++ and Java but also a lot of variations. If you keep in mind what I listed you should feel pretty comfortable coming from Java to C++. The syntax is quite identical but when it comes to memory, the way things work can be very different.
There are some factors you need to get used to using headers.
- In Java, you describe your class and that class in the same file to be implemented.
- In C++ the class description is in the header, and the functions are implemented in the.cpp file.
You can read into the preprocessor as well. All statements starting with # (# include, # define, # if, etc.) are macros for preprocessors. They are executed at compile-time (or before compile-time actually) and do not run time. Until it runs through the compiler they are used to turn the code.C++ features are “traditional,” and which are not.
You should not use old-style casting (c-style casting with parentheses, as in Java), but use the static cast, dynamic cast, in-build instead.
Unfortunately, C++ has many features in common with Java, and having a working knowledge of C++ is simple for a Java programmer. But C++ is a language that is much more complex than Java. … You’ll need to read more about the C++ sections that were inherited from C to use such compilers.
Required Time For Learning:-
C++ is a little complex than Java since it carries with it all those features and internal memory management that are difficult to understand. You can’t expect expertise in a few weeks or even months to learn C++.
