Comments
Inline comments
Should be of the form //.
Example:
uint32_t work_hours; // Includes extra hours
Multiline comments
Should be of the same form mentioned before, expanded throughout as many lines as necessary.
Example:
//
// Quick-sort implementation.
// Uses iterators from the begining and end
// of the container.
//
Notice the leading and the trailing // above, its recommended to use them so they better separate the code from your comment.
DO NOT, use /* */, inline or multiline comments.
