                                            Compiling and Running Your First C Program  in this topic  I ntroduces the basics of C programming in an easy-to-follow format, and includes some exercises you can try on your own to get you started how to save the source code in a file, and how to compile and run it. Open a text editor and add the above-mentioned code. Save the file as  hello.c Open a command prompt and go to the directory where you have saved the file. Type  gcc hello.c  and press enter to compile your code. If there are no errors in your code, the command prompt will take you to the next line and would generate  a.out  executable file. Now, type  a.out  to execute your program. You will see the output  "Hello World"  printed on the screen. $ gcc hello.c $ ./a.out Hello, World! e gcc compiler is in your path and that you are running it in the directory containing the source file hello.c.

so when we install GCC on Windows, then we  need to install MinGW. so  install MinGW,.  MinGW installation program, which should be named MinGW-<version>.exe. when we installing  Min GW, at  a minimum, so you have to necessary to install  GCC -core, g++  binutils, and the MinGW.
