difference in the style of giving comments between C and C++ : Is there any difference between a commenting style between C(`/*..*/`) and C++(`//`)?

**MISRA C says** 

> Rule 2.2 (required): Source code shall only use /* … */ style
> comments.

**MISRA C++ says**

    Rule 2.7.1 (required): The character sequence /* shall not be used with c style comments.

Can any one explain me what could be the difference?
