How can I execute
a.exe using the Cygwin shell?
I created a C file in Eclipse on Windows and then used Cygwin to navigate to the directory. I called gcc on the C source file and
a.exe was produced. I would like to run

./a.exe at the prompt

you should just be able to call it by typing in the file name. You may have to call ./a.exe as the current directory is usually not on the path for security reasons.

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.

To execute a file in the current directory, the syntax to use is:
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.

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.

Just call it
Make sure it will be found (path).

When you start in Cygwin you are in the "/home/Administrator" zone, so put your a.exe file there.
Then at the prompt run:
It will be read in by Cygwin and you will be asked to install it.
