Mac OS X Installation: If you are a Mac user,you have to download Xcode.After saving the file with ‘.cpp’ extension, go to Build menu and choose the Build and Run option.Now write your C++ program in this empty file and save the file with a ‘.cpp’ extension.After successfully installing Code::Blocks, go to File menu -> Select New and create an Empty file.Once you have downloaded the setup file of Code::Blocks from the given link open it and follow the instruction to install. To download Code::Blocks you may visit this link. Windows Installation: There are lots of IDE available for windows operating system which you can use to work easily with C++ programming language.This command will run your program in the terminal window.Now to run your program you have to run the below command. After executing the above command, you will see a new file is created automatically in the same directory where you have saved the source file and the name of this file is the name you chose as any-name.We will run the above command as: g++ helloworld.cpp -o hello In our case, we choose any-name to be “hello”. This name will be assigned to the executable file which is created by the compiler after compilation. In our case, the name is “helloworld.cpp” and any-name can be any name of your choice. filename.cpp is the name of your source code file.Then you have to run the below command to compile your file: g++ filename.cpp -o any-name Now you have to open the Linux terminal and move to the directory where you have saved your file.We have written a program to display “Hello World” and saved it in a file with the filename “helloworld.cpp” on desktop. Write your program in a text file and save it with any file name and.CPP extension.
In further steps, we will learn how to compile and run a C++ program on Linux using GCC compiler.
This command will install all the libraries which are required to compile and run a C++ program.You may also run the below command: sudo apt-get install build-essential This command will install the GCC compiler on your system.
You have to first run the below two commands from your Linux terminal window: sudo apt-get update.To install and work with the GCC compiler on your Linux machine, proceed according to below steps:
Below are the details about setting up compiler on different platforms. For compiling a C++ program we will need a C++ compiler which will convert the source code written in C++ into machine codes. In other words, we can say that it converts the source code written in a programming language into another computer language which the computer understands. A compiler is a computer program which converts high-level language into machine understandable low-level language.
