Can you Learn C++ without Learning C

I can answer this question straight away by either saying a ‘Yes’ or ‘No’. But, by simply saying a ‘Yes or No’ won’t justify the answer. It all depends upon the ability of the person who is learning C++. But, it can end up like you learn to drive an automatic car without knowing the manual driving lessons. When circumstances arrive, you may have to simply say “I don’t know”. Therefore, it is always better if you learn the basics rather than moving ahead baseless. After all, C++ is just an improvement on C. Now, let me help you with all the points that will add more justification, comparison, and reason. Let’s navigate through these points. 

Why should you learn C?

Learning C programming has a lot of benefits. But first, you need to understand the underlying architecture of how things work with C is very important. 

C was initially developed by Dennis Ritchie between 1969 and 1973 as a procedural programming language. The main purpose of developing this system programming language was to write an operating system. Some of the features which make C language suitable for system programmings like an operating system or compiler development are its: 

  • Low-level access to memory
  • A simple set of keywords
  • and a Clean style

Like in the case of learning to drive an automatic and manually driving car, if you know to drive a manual car, it will make driving an automatic car all the easier. Similarly, if you learn C programming first, it will help you to learn any modern programming language very well. 

Advantages of Learning C 

  • C language helps you to understand the underlying architecture of an operating system like pointers, working with memory locations, etc.
  • C can be called as a middle-level language, because, it combines all the features of Low-Level machine-understandable assembly languages and High-Level user-friendly languages. Language C reduces the gap between the low-level and high-level languages and can be used for writing operating systems as well as doing application-level programming.
  • It allows you to develop portable and firmware applications. The C language was developed with an objective of writing system software and therefore, it is ideal for developing firmware systems.
  • Learning C language first helps you to understand the fundamentals of Computer Theories like Computer Networks, Compiler Designing, Computer Architecture, and Operating Systems. If you’re working on these theories, it requires a good knowledge of C programming. 
  • Also, C helps you to understand machine-level details. So if you want to work as a networking engineer or a system administrator, learning C language is a must to work with CPU cache, memory, and network adapters. 
  • Learning C is easy as it has fewer libraries in comparison with other high-level languages. It will clear out programming concepts to a great extent as in C you have to write a lot of things from scratch. This will not only help in building your analytical skills but will learn to implement some basic operations all your own. 
  • Programs written and compiled in C can be executed faster than other programming languages. Also, not having any additional processing overheads such as garbage collection or preventing memory leaks, etc makes C more advantageous. While a programmer must take the initiative to do all the things his own. 
  • C uses embedded programming extensively where it is used to control micro-controllers such as auto-motives, Robotics, Hardware, etc.
  • C creates a list of instructions for a computer to follow and therefore it is easy to learn the language. 

Key Differences between C and C++

C++ language is a subset of the C language and was first designed as an extension of C. 

When C has procedural language features, C++ has both procedural and object-oriented programming features like polymorphism, inheritance, abstraction, encapsulation, etc.

Best C/C++ IDEs

C and C++ are very popular and actively used across various applications and systems worldwide. Both languages are still actively used by most programmers because of the powerful set of features and the excellent security of C++. One of the best things about C++ is its IDE or the Integrated Development Environment. This environment offers the developers a digital environment to develop software, hardware and games with the built-in function like code completion, integration, debugging, and all the way to compiling and syntax highlighting. During the year 2020 and beyond, the developers will have some of the top and the best C++ IDE’s. Some of these C++ IDEs can also be used for C programming. They are:

Eclipse- An easy-to-use powerful IDE that offers open-source utility and functionality. It is also one best C++ IDE for Windows Applications. 

Code:: Blocks- It is a free C/C++ IDE that has all the features to meet the demands of the C and C++ developers. This IDE can be used on Windows. 

GNAT Programming Studio-  Also known as GPS, GNAT Programming Studio is a highly advanced Free IDE that simplifies the interaction between the software and its developers. 

Visual Studio Code: Developed by Microsoft and based on an Electron framework, Visual Studio Code is an open-source IDE designed for Windows, macOS, and Linux. It is the most popular developer environmental tool and best IDE among others with excellent customization options. 

Similarly, other popular and the best C++ IDE for Windows, Linux, and Mac OS X are CodeLite, Dev C++, Qt Creator, Sublime Text, Linx, MonoDevelop, CLion, Anjuta, and C++ Builder

If you have the willingness to learn C or C++ languages regardless of whether you’re just a beginner or a C or C++ Programmer, IDEs are best to make your programming career easy. 

C++ Compilers

C++ Compilers are necessary when you start doing a specific program as it will make your job easier and for computers to understand the input given. There are too many C++ compilers which can be recommended that are either available for free or for a price. The higher the prices, it will reflect in the features offered to you. 

While the C++ world is just too large and too much new is happening, you will require a C++ certification to fight the competition in the industry. 

Features & Properties of C

  1. Procedural
  2. System programming language
  3. Does not support classes and objects
  4. Bottom-up approach
  5. Supports pointers

Features & Properties of C++

  1. Object-oriented
  2. Faster Execution and Speed
  3. Rich library support in the form of the standard template library
  4. Supports Pointers & References
  5. Bottom-up approach
  6. Compiled

Although C++ is much more advanced and superfast than C if you want to make your journey easier to start from the basics. It will help your learning not only C++ but also any other languages easier. So, let’s start from the beginning with an extremely simple C program and build up from there. There are numerous benefits of learning to c/c++ language for your career. It is recognized worldwide and used in a multitude of applications. It will help you secure a great career in the future.

What is SWIFT?

SWIFT is an alternative to Objective C and a Protocol Oriented Programming System.SWIFT is used by Apple Inc in the development of Apple products like iOS, OS X, watchOS, tvOS and Linux etc.

When it was developed?

The 1.0 Swift was released on the 9th of September 2014.

 

What are the main features of SWIFT?

Safety

Swift removes entire classes of unsafe code. Integers are checked for overflow, variables are always initialized before use and memory is managed automatically.

Another feature is that Swift objects can never be nil, which means it can generate a compiler error, as soon as you write bad code. Problems can be fixed as code is written, which will reduce your time and money that you will spend on fixing errors.

It triggers a runtime crash if a NIL optional variable has been used which will help to avoid the bug, or to fix it sooner entirely in Swift code.

Fast and Powerful

Swift has greatly improved by dropping legacy C conventions. It uses the incredibly high-performance LLVM compiler to transform Swift code into optimized native code.

Swift has made Object sorting considerably quicker and faster than Python. It provides object-oriented features like protocols, generics and classes, thereby giving Cocoa and Cocoa touch developers the power and performance they demand.

Objective-C Interoperability

Swift’s complete compatibility with Objective-C allows you create a project that includes files written in either language. You can develop apps that have a mixed-language codebase.

Also, you can implement part of your app’s functionality by using the Swift’s latest features and incorporate it seamlessly back into your existing Objective-C codebase.

 

What are the fundamental difference between SWIFT and Objective C?

Readability

The number one advantage to choosing Swift is arguably because of its clean syntax, which makes it easier to read and write. The number of code lines needed to implement an option on Swift is a lot fewer than for Objective-C.

The reason for this is because Swift drops many legacy conventions, such as semicolons to end lines or parentheses that surround conditional expressions inside if/else statements.

Another major change is that method calls do not sit inside each other resulting in a bracket mess. Instead, method and function calls in Swift use the comma-separated list of parameters within parentheses. As a result, the code is cleaner with a simplified syntax.

Swift code more closely resembles plain English, which makes writing code more natural while enabling developers to spend far less time looking for problematic code.

This readability also makes it easier for existing programmers from JavaScript, Java, Python, C#, and C++ to adopt Swift into their toolchain.

Maintenance

It’s not possible for Objective-C to evolve without C evolving first. Contrarily, Swift does not have these dependencies, which makes it a lot easier to maintain.

C requires programmers to maintain two code files in order to improve the build time and efficiency of the code, which also carries over to Objective-C.

Swift, however, drops this two-file requirement, combining the Objective-C header (.h) and implementation files (.m) into a single code file (.swift). In Objective-C, you have to manually synchronize method names and comments between files.

While with Swift, programmers can spend more time creating app logic and improving the quality of their code, comments, and features that are supported.

Safer Platform

In the competitive mobile app marketplace, developing a secure app should be a priority. Swift’s syntax and language constructions exclude the several types of mistakes possible in Objective-C.

This stability means that there will be fewer crashes and cases of problematic behavior. It doesn’t prevent programmers from writing bad code, but rather makes it less likely to make mistakes. This adds an extra layer of quality control during development.

Swift takes the nil code, and generates compiler error when programmers write bad code. With Swift, you can compile, and fix the errors while writing the code, which is not possible with Objective-C. As a result, Swift works better and faster compared to Objective-C when it comes to bug testing.

All this gives reason to consider Swift as a safe and secure programming language.

Less Code & Less Legacy

With Objective-C, there are many issues that cause app crashes. Swift provides code that is less error-prone because of its inline support for manipulating text strings and data. Additionally, classes aren’t divided into two parts; the interface and the implementation. This cuts the number of files in the project in half, which makes it much easier to handle.

Swift ultimately requires less coding efforts when writing repetitive statements or causing string manipulation.

When working with Objective-C, you’ll need to combine two strings which make it lengthy. With Swift, you just need to add the ‘+’ sign to join two strings.

Speed

Swift also provides various speed advantages during development, in turn, saving on costs. A complex object sort, for example, will run 3.9x faster than an implementation of the same algorithm in Python. That’s also better than Objective-C, which is 2.8x faster than the Python version.

Its performance approaches the one of C++ which is considered the fastest algorithm calculation arithmetics. In December 2014, Primate Labs published a report on Swift and C++ performance. Apple has made it evident that they’re dedicated to improving the speed at which Swift can run app logic.

Swift Supports Dynamic Libraries

Dynamic libraries are executable chunks of code that can be linked to an app. This feature allows current Swift apps to link against newer versions of the Swift language as it evolves over time. Dynamic libraries in Swift are directly uploaded to the memory, cutting down on the initial size of the app and ultimately increasing app performance.
