How many days do I need to learn C programming?
You can easily learn C language in less than a month if you are dedicated enough and learn it in the right order. Follow these steps in order to excel in this language in a short time.First of all, select a right source with which you can understand the programming language in an easier way. Some of the good resources are CodesDope, edX, Cprogramming and Tutorials Point.Second, there should be a perfect order in which you learn the topics (so that it becomes a bit easier and takes lesser time)Practice is the most important element in order to become good at any programming language. So practice a lot. Practice questions related to a topic after you have completed that topic.Only move to the next topic if you have mastered the previous topic.You can complete the above steps in less than a month. Let’s assume that you took at max one month to learn the language. Now in order to become better at it, you need to practice to lot and improve your coding skillsAfter you have learnt the programming language, go to some competitive sites like Hackerrank and improve your coding skills by learning and applying more and more algorithms.Never let a doubt reside in your mind. Get your doubts cleared as soon as you face one. There are many discussion forum sites like Stack Overflow, Code Project, Codesdope: Discussion Forum and Code Guru.After all this, you can do some projects in C or anything which interests you to get a little more into the language.
How do I write a program for finding the square root of a number without using the sqrt function?
Simple logic is if you keep on adding odd numbers then the number of times you add odd number will be the square root of the summation of 1 to that odd numberFor example1 = 1 square of 11 + 3 = 4 square of 2,,adding two times1 + 3 + 5 = 9 square of 3 adding three timeshere is my simple code#include
As a beginner, should I learn C or Python as my first programming language?
Depends on what you want to do with your life and how seriously you take programming.If you're programming for fun, perhaps you should focus just on Javascript, Python and Ruby. Not because they're toy languages - far from it - but because they're the kind of language that you go to make things that Just Work (tm). All three languages are modern, powerful and flexible. And you just might land a pretty good job if you know how to work with any of them.If you want to develop a career as a programmer but want to work in a predictable career, then please focus on Java or C# (or perhaps SAP's ABAP). There's nothing wrong with that, it's just a personal choice. You'll work for large companies and you can make good money. But that's not where startups founders go.If you want to work with mobile technologies, focus on Objective C, Swift, C or Java. Enough said.If you want to become a entrepreneur and focus on writing the next Facebook, it's about the same as with "programming for fun" (and that's not a coincidence).If you're serious about programming and want to become a master, then forget about specific languages, and do yourself a favor: focus first on algorithms and data structures. Go read a good book like something from Aho or Sedgewick. Study it thoroughly. Do all exercises (hey, I'm kidding, but I'm sure you got my point). Go read something like Programming Pearls, by Jon Bentley. Go read some books by Brian Kernighan and Ken Thompson. And then go read Knuth's The Art of Computer Programming. (please tell me if you survived it).But PLEASE! don't get me wrong :-) These guys wrote about 40, 30, 20 years ago, almost EVERYTHING you need to know to have a proper appreciation of how computers work, and how they do their things. Studying great books on programming is amazing - if you love to program.
What is the difference between programming languages such as Python, C, C++ and Java?
My way of looking at it is as follows: [1]Imagine you had to write a set of instructions in English which are then to be translated to Italian.Writing in C++ is like writing: If the (integer) time is past (integer) 9 put on some (adjective) work (noun) clothesWhile writing in Python is like writing If the time is past 9 put on some work clothesIn the case of C++ one specifies the "type" of things and so there is less ambiguity about what the instruction means and errors can be "caught" even before the Italian translator even attempts to translate to Italian.In the case of Python, one doesn't specify these types and the instruction reads a bit more naturally and is shorter in length. The Italian translator kind of has to figure out whether "time" is a noun or an integer or whether "work" is a noun or an adjective.The example allows one then understand these differencesIn PrincipleC++ is a "statically typed" language, while Python is a "dynamically typed" language. In one case, the types of the main components of the set of instructions (the computer program) are explicitly declared while in the other case they aren't.In Practice2. C++ is "faster" than Python C++ is typically a "compiled" language while Python is typically an "interpreted" language. With C++, the instructions are very well understood with all types specified and so they are translated into machine code (they are compiled) and executed unambiguously by the computer ...while with Python a separate computer program has to figure out what the Python instructions really mean [2,3] and how to "interpret" them to produce an output. The overhead of running this extra program versus simply just running the well defined machine code typically ensures that C++ runs much faster than Python.3) Python is more concise than C++Though this is certainly not an absolute truth, the example also shows one of the reasons why Python code tends to be shorter than that written in C++ (i.e. there is no need to declare types explicitly and this literally saves space in written code). Smaller code size for the same task leads to "rapid prototyping" and this is partly why one would use something like Python when speed of development is important.[1] More expert Computer Scientists are welcome to correct my analogy.[2] To be precise, the Python is first converted to a different representation ...but that's not so important.[3] Referring to the standard CPython implementation
When entering a credit card number, do you have to put spaces between each four digits?
Most sites/programs prefer them all run together but if you put spaces it probably defaults them to no spaces on their end. I'm sure you're fine but in the future, just run em all together.
Can anyone convert this C++ code to Java?
C++ and Java are two different types of language . They have their own syntax .Both the language are object oriented . Still these can’t be merged together .One and only reason is C++ supports both object oriented and procedural approach. Multiple inheritance is used . Pointers can be used .But JAVA is 100% object oriented . You need to use class for all of it’s program . No multiple inheritance in java , pointers are not valid .So converting a c++ code to a java code or vice versa can be a tough job .Hello world in c++#include
For a mechanical engineer, which programming language is better to learn, C, C++, Java or Python?
There is not any specific language for mechanical guys , when you starts learning programming language , you put steps into the IT World. If you want to make a career in IT Sector then you have to carefull about choosing a programing language. So my advice is that first go through the languages like C and I can refer you one book “ Let us C by Yeshwanth kanetkar” this makes you capable to understand the basic pillers and core terminology of pl's and this makes you capable to think about in which technology you want to go.As now , there’r 5 technology which is more liable and through which you can get job more frequently:PHPJavaIf Java is understandable then you can also choose Android as a careerNode js/Angular js (frontend) + Java/PHP/pythonPython for data scientist/developerAnd when you go through these then you'r also introduced to the Database world . So if though your thought process might be change then you can also become a database developer likeOracle developerMySQL developer~~ Best of luck ~~

Can I run C++ code on ATmega16?
Yes, you can. C++ is supported on AVR. If you add the extensions .cc, .cpp or .C for a source file, the C++ compiler will be invoked called as avr-c++.Although since currently there is no support for libstdc++, standard support library is needed for a complete c++ implementation.This imposes a no. of restrictions on C++ programs, these are :None of C++ standard functions, classes and template classes are available.Operators new and delete are not implemented.Some of supplied include files are not C++ safe i.e., they need to be wrapped into extern“C ” {….}Exceptions are not supported. Since exceptions are enabled by default in C++ frontend , they explicitly need to be turned off using -fno- exceptions in compiler options. Failing this, linker will complain about an undefined external reference to __gxx_personality_sj0.However, constructors and destructors are supported including global ones.
