C For Mac Programming

-->

However, 'C' programming has always been a favorite bull's eye to the. Code editor developed by Microsoft for Windows, Linux and Mac OS. Today, we bring you a line up of text editors for Mac users that are. For tons of programming languages and file types among other features.

In this article, you'll use Visual Studio to create the traditional 'Hello World!' program. Visual Studio is a professional Integrated Development Environment (IDE) with many features designed for .NET development. You'll use only a few of the features in Visual Studio to create this program. To learn more about Visual Studio, see Getting Started with Visual C#.

Note

Your computer might show different names or locations for some of the Visual Studio user interface elements in the following instructions. The Visual Studio edition that you have and the settings that you use determine these elements. For more information, see Personalizing the IDE.

Create a new application

Start Visual Studio. You'll see the following image on Windows:

Select Create a new project in the lower right corner of the image. Visual Studio displays the New Project dialog:

Note

If this is the first time you've started Visual Studio, the Recent project templates list is empty.

On the new project dialog, choose 'Console App (.NET Core)' and then press Next. Give your project a name, such as 'HelloWorld', then press Create.

Visual Studio opens your project. It's already a basic 'Hello World!' example. Press Ctrl + F5 to run your project. Visual Studio builds your project, converting the source code into an executable. Then, it launches a command window that runs your new application. You should see the following text in the window:

Press a key to close the window.

Start Visual Studio for Mac. You'll see the following image on Mac:

Note

If this is the first time you've started Visual Studio for Mac, the Recent projects list is empty.

Select New in the upper right corner of the image. Visual Studio for Mac displays the New Project dialog:

On the new project dialog, choose '.NET Core', and 'Console App' and then press Next. You'll need to select the target framework. The default is fine, so press next. Give your project a name, such as 'HelloWorld', then press Create. You can use the default project location. Don't add this project to source control.

Visual Studio for Mac opens your project. It's already a basic 'Hello World!' example. Press Ctrl + Fn + F5 to run your project. Visual Studio for Mac builds your project, converting the source code into an executable. Then, it launches a command window that runs your new application. You should see the following text in the window:

Press a key to end the session.

Elements of a C# program

Let's examine the important parts of this program. The first line contains a comment. The characters // convert the rest of the line to a comment.

You can also comment out a block of text by enclosing it between the /* and */ characters. This is shown in the following example.

A C# console application must contain a Main method, in which control starts and ends. The Main method is where you create objects and execute other methods.

The Main method is a static method that resides inside a class or a struct. In the previous 'Hello World!' example, it resides in a class named Hello. You can declare the Main method in one of the following ways:

  • It can return void. That means your program doesn't return a value.
  • It can also return an integer. The integer is the exit code for your application.
  • With either of the return types, it can take arguments.

-or-

The parameter of the Main method, args, is a string array that contains the command-line arguments used to invoke the program.

For more information about how to use command-line arguments, see the examples in Main() and Command-Line Arguments.

Input and output

C# programs generally use the input/output services provided by the run-time library of the .NET Framework. The statement System.Console.WriteLine('Hello World!'); uses the WriteLine method. This is one of the output methods of the Console class in the run-time library. It displays its string parameter on the standard output stream followed by a new line. Other Console methods are available for different input and output operations. If you include the using System; directive at the beginning of the program, you can directly use the System classes and methods without fully qualifying them. For example, you can call Console.WriteLine instead of System.Console.WriteLine:

For more information about input/output methods, see System.IO.

C++ is a middle-level programming language developed by Bjarne Stroustrup starting in 1979 at Bell Labs. C++ runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX. This C++ tutorial adopts a simple and practical approach to describe the concepts of C++ for beginners to advanded software engineers.

Why to Learn C++

C++ is a MUST for students and working professionals to become a great Software Engineer. I will list down some of the key advantages of learning C++:

  • C++ is very close to hardware, so you get a chance to work at a low level which gives you lot of control in terms of memory management, better performance and finally a robust software development.

  • C++ programming gives you a clear understanding about Object Oriented Programming. You will understand low level implementation of polymorphism when you will implement virtual tables and virtual table pointers, or dynamic type identification.

  • C++ is one of the every green programming languages and loved by millions of software developers. If you are a great C++ programmer then you will never sit without work and more importantly you will get highly paid for your work.

  • C++ is the most widely used programming languages in application and system programming. So you can choose your area of interest of software development.

  • C++ really teaches you the difference between compiler, linker and loader, different data types, storage classes, variable types their scopes etc.

There are 1000s of good reasons to learn C++ Programming. But one thing for sure, to learn any programming language, not only C++, you just need to code, and code and finally code until you become expert.

Hello World using C++

Just to give you a little excitement about C++ programming, I'm going to give you a small conventional C++ Hello World program, You can try it using Demo link

C++ is a super set of C programming with additional implementation of object-oriented concepts.

There are many C++ compilers available which you can use to compile and run above mentioned program:

  • Apple C++. Xcode

  • Bloodshed Dev-C++

  • Clang C++

  • Cygwin (GNU C++)

  • Mentor Graphics

  • MINGW - 'Minimalist GNU for Windows'

  • GNU CC source

  • IBM C++

  • Intel C++

  • Microsoft Visual C++

  • Oracle C++

  • HP C++

It is really impossible to give a complete list of all the available compilers. The C++ world is just too large and too much new is happening.

Applications of C++ Programming

As mentioned before, C++ is one of the most widely used programming languages. It has it's presence in almost every area of software development. I'm going to list few of them here:

  • Application Software Development - C++ programming has been used in developing almost all the major Operating Systems like Windows, Mac OSX and Linux. Apart from the operating systems, the core part of many browsers like Mozilla Firefox and Chrome have been written using C++. C++ also has been used in developing the most popular database system called MySQL.

  • Programming Languages Development - C++ has been used extensively in developing new programming languages like C#, Java, JavaScript, Perl, UNIX’s C Shell, PHP and Python, and Verilog etc.

  • Computation Programming - C++ is the best friends of scientists because of fast speed and computational efficiencies.

  • Games Development - C++ is extremely fast which allows programmers to do procedural programming for CPU intensive functions and provides greater control over hardware, because of which it has been widely used in development of gaming engines.

  • Embedded System - C++ is being heavily used in developing Medical and Engineering Applications like softwares for MRI machines, high-end CAD/CAM systems etc.

This list goes on, there are various areas where software developers are happily using C++ to provide great softwares. I highly recommend you to learn C++ and contribute great softwares to the community.
