An In-Depth Look At C++ Environment Setup With Examples.<\/strong><\/p>\n

In this Free C++ Training Series<\/strong><\/a>, we will learn more about C++ Environment Setup in this tutorial.<\/p>\n

We will look into the details about how we can execute C++ programs. For this, we will need to set up an environment on our local machine or we can also do it by using other means.<\/p>\n

C++ programs can be executed on a variety of operating systems like Windows, Linux, Mac OS, etc. Each operating system has its own features & behavior and based on that the approach of setting up a C++ environment will differ accordingly.<\/p>\n

<\/strong><\/em><\/p>\n

L<\/strong>et us now explore the different ways of executing our C++ programs!!<\/strong><\/em><\/p>\n

\"C++<\/a><\/p>\n

Local Environment<\/h3>\n

In order to learn C++ effectively, we need to practice programs before we begin with C++ programming. For this, we need to have a proper environment on our local machine from where we can write C++ programs, compile them and later execute them.<\/p>\n

As a part of the local environment setup, we need two most important software on our machine as mentioned below:<\/strong><\/p>\n

#1) Text Editor<\/span><\/h4>\n

Firstly, we need to write programs and save each file with a \u2018.cpp\u2019 extension. In order to write these programs, we need a text editor on our machine. Any text editor that allows us to input text should work. It can be as simple as a notepad or an advanced editor like Notepad++. We need this editor to write programs.<\/p>\n

Once we finish writing a program, we save this file with an extension \u2018.cpp\u2019 and then pass it on to compiler for compiling. This file with .cpp extension is called the \u2018source code file\u2019.<\/p>\n

Given below is a screenshot of a Notepad++ Editor that is used to write C++ programs:<\/strong><\/p>\n

\"Notepad++<\/a><\/p>\n

#2) Compiler<\/span><\/h4>\n

Once we have the C++ program ready, we need to compile the program and execute it. We use a software program called \u201cCompiler\u201d to compile the program.<\/p>\n

A compiler is a software that converts a program written in a high-level language (in this case C++) into low-level machine language instructions which the computer can understand. Later, the computer executes each of these instructions to produce the desired results. This set of low-level machine instructions is called an Object code.<\/p>\n

Thus in simple terms, compilation can be defined as the conversion of source code into the object code.<\/p>\n

In the upcoming section, we will look into the details of setting up compiler on different platforms.<\/p>\n

Setting C\/C++ Compiler<\/h3>\n

Linux Operating System<\/span><\/h4>\n

We need to type the following command in order to ensure that our Linux Operating System has the correct version of C++ compiler.<\/p>\n

g++ -v<\/pre>\n
If the compiler is installed correctly on this Linux system, then the above command will launch the C++ compiler and print its version. If an error occurs, then it is required that we read the error and check the documentation again and correct the setup accordingly.<\/p>\n
Once the compiler is set up correctly, we can compile any C++ program by giving the following command:<\/strong><\/p>\n
g++ filename.cpp<\/pre>\n
If the code is error-free, an executable \u201ca.out\u201d will be generated, which when executed will provide us with the desired results.<\/p>\n
.\/a.out<\/pre>\n
Note:<\/strong><\/span> The above command to execute a.out may differ depending on the version of Linux.<\/p>\n
 Windows Operating System<\/span><\/h4>\n
C++ is very vast and so are the compilers available for C++. We have a lot of compilers that are available in the Windows out of which some are freely available while some are paid.<\/p>\n
 Some of the compilers that are freely available are listed below:<\/strong><\/p>\n
