Its fairly simple actualy, you can use system("command") to see its version(dont forget to include stdlib.h) like this:

system("java -d64 -version");

and on your console you will get the reaply, if it says :

This Java instance does not support a 64-bit JVM. Please install the desired version

this means it's not a 64-bit version.

you can read much more about it in here: detect jre bit version
