c - gcc compiler in Cygwin output .exe -

just starting in c, , learning basics. have created simple program when compiled, expected compile a.out gcc compiling a.exe.

gcc on windows defaults creating file named a.exe on windows, because .exe extension important - file name a.out not recognized executable program on windows. default output named a.out.exe different a.out anyway, sensible produce file named a.exe instead.

a.exe less keypresses, too.
