How do I write in-code comments and documentation in a proper way? Is there any standard for this?

Question

I want to add documentation in my code by means of comment lines.
Is there any standard format for this?

For example, consider the code below:

class Arithmetic
{
    // This method adds two numbers, and returns the result.
    // dbNum1 is the first number to add, and dbNum2 is second.
    // The returning value is dbNum1+dbNum2.
    static double AddTwoNumbers(double dbNum1, double dbNum2);
}

For this example code, is there any better way of writing the comment lines?

For c++ there isn't a standard, like javadoc, but certain documentation tools are popular and common to use. Off the top of my head, I can mention doxygen.

Doxygen also supports the familiar javadoc style, ie:

/**
   This method adds two numbers, and returns the result.
   @param dbNum1 is the first number to add
   @param dbNum2 is second.
   @return The returning value is dbNum1+dbNum2.
*/
static double AddTwoNumbers(double dbNum1, double dbNum2);
