How to use Doxygen to document local variables within C++ functions

Question

For example, in my function

//starting code with doxygen documentation
/** The main function. I will now try to document variables within this main function*         


        

Answer 1

While you can put comments in the body of a function and let them appear as part of the function documentation like so

/** @file */

/** The main function. I will now try to document 
 *  variables within this main function.
 */
int main()
{
  /** an integer array. */
  int arr[];

  /** An endless loop */
  for (;;) {}

  return 0;
}

This is generally not recommended as others already pointed out. If you want (as a developer) to read the sources along with the documentation, you can better use normal C comments in the body

/** @file */

/** The main function. I will now try to document 
 *  variables within this main function.
 */
int main()
{
  /* an integer array. */
  int arr[];

  /* An endless loop */
  for (;;) {}

  return 0;
}

along with setting INLINE_SOURCES to YES.
