C-Decompiler

C-Decompiler provides you with an intuitive and easy to handle application that aims to help programmers decompile portable executable files and retrieve the original C / C++ source code.
In the decompiling process a reverse engineering operation is performed, which allows the user to view the program code in a human readable form. C-Decompiler can output the code representation that corresponds to your EXE file, making it intelligible to users.
One major drawback of this application is related to the supported compiler versions, which is not quite extended. VC6.0, VC2003, VC2005 and VC2008 are the only versions of Visual Studio that C-Decompiler can handle and having to decompile an executable file created with a more recent version is not possible, as the application triggers an error message and immediately exists.
One of the pluses is the ease of use, which makes it suitable even for beginner programmers. The GUI in neatly organized and split into three panes, enabling you to view the functions, classes and the code in a structured manner.
As far as the usage is concerned, the application requires you to browse for the input file in your computer and once it is loaded, press the 'Decompile' button to proceed.
The process is usually finished in a matter of seconds, but this depends on the size of the input file. The extracted code can be viewed within the main window but, unfortunately, no option is available to allow the user to copy the output to the clipboard or save it as a text file.
C-Decompiler comes in handy for analyzing executable files created with older versions of Visual Studio. Considering its capabilities and comparing advantages and drawbacks, you might want to consider searching for a more reliable and full-featured tool.
