first of all there is nothing like debug or release this is only a default setting provided by the visual studio app wizard you can change the setting and make the debug as release or vice versa if you want you can create your own version with any name or can delete the existing on.
now here is difference between the default version debug and release.

Debug :
1. preprocessor macro _DEBUG is enabled.
2. compiler code optimization is off.
3. ASSERT is enabled.
4. Debug version of windows library and dll is used.

Release :
1. preprocessor macro NDEBUG is enabled.
2. compiler code optimization is ON.
3. ASSERT is disabled anything inside of ASSERT wan't be executed.
4. Release version of windows library and dll is used.

and one big difference becoz of that sometime code build in the debug is work and release version code do not work or crashed:

all variable in the debug version initialize from a known value that is not happen in the release other cause is on release version compiler optimization setting is ON.
