I am trying to learn C++ and I understand most of it so far but have no idea what -> does. Example from tut 31: glTexCoord2f( pTri->m_s[k], pTri->m_t[k] );

That is pointer to structure member operator and it references struct/class/union field through a pointer. Basically, it''s the same thing as ''.'' for a class object.

Normally you would write something like this:
myStruct.someVariable
When using a pointer you just change . to ->

That''s a _free_ eBook. Download it, read it. Soon it will all become apparent.

Just to add :

The -> operator is used a short hand method of accessing members through pointers.





It saves you from having to deref''ing the pointer first.
