use jar.exe -cvfm <jar filename> <manifestfile> -C <directory and its file to be jared>

manifest file should contain

Main-Class:<user main class>

example
Main-Class:a.b.Hello.class

>> I want to create an exe file using C/C++ where in I can open this jar file.

You need to ask in the C/ C++ topic-area for writing code through which you can execute a process (like the Runtime.exec () API in Java). Just make sure that JAR files have Java 2 (javaw.exe or whatever) as the default application for opening them and not something like Winzip.

You can maybe (depending on classes used) compile it into an executable using gcj
