Thomas wrote      Apparently  gcc doesn t behave like the one described in The C Programming language   It does in general   For your program to run on Windows it needs to end in  exe   the C Programming language  was not written with Windows programmers in mind   As you ve seen  cygwin emulates many  but not all  features of a POSIX environment

Apparently  gcc doesn t behave like the one described in The C Programming language  where it says that the command cc helloworld c produces a file called a out which can be run by typing a out on the prompt    A Unix hasn t behaved in that way by default  so you can just write the executable name without    at the front  in a long time  It s called a exe  because else Windows won t execute it  as it gets file types from the extension

gcc under cygwin does not generate a Linux executable output file of type   ELF 32-bit LSB executable   but it generates a windows executable of type  PE32 executable for MS Windows  which has a dependency on cygwin1 dll  so it needs to be run under cygwin shell  If u need to run it under dos prompt independently  they cygwin1 dll needs to be in your Windows PATH   -AD

To execute a file in the current directory  the syntax to use is    foo  As mentioned by allain    a exe is the correct way to execute a exe in the working directory using Cygwin   Note  You may wish to use the -o parameter to cc to specify your own output filename  An example of this would be  cc helloworld c -o helloworld exe
