Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Difference between -> and .

Hello guys! I just want to know what is the difference between -> (hyphen and comparison sign to the left) and . (dot). Also I don't really know when and how can I use :: (double colon). I'm new to this language, and I couldn't figure it out.

Many thanks for help!

Rama (C++ God) wrote a great article about this matter :). Please check it out here:

"->" means it is a pointer pointing to a reference on memory that might or might not exist.

"." means it is a container that contains actual data (example struct)

:: means it is a class name or namespace.
