Why isn’t C commenting style preferred in C++? C commenting style definitely looks neater and more readable than the C++ commenting style.
/* comments in C++ are just as good as // comments. In fact, I use both of them interchangeably. The main difference between the two is that // are used in very short comments that do not exceed a single line of text.
On the other hand, /* comments are more useful when you have longer comments that spread across two or more lines. In addition, you can use them when you want to make your C++ code compatible with C compilers or when you want to avert the problems associated with the interpretation of // as a file name (some mail clients and Web browsers tend to do that). Sometimes, when you need to hide substantial parts of your source file (e.g., for debugging purposes), /* are also useful.
