Im having a little problem with this code : Dev cpp returns this error: But if i do this (i know its the bad way) : It works ! Any ideas what im doing wrong ? -.-!!

TEMP1 is a pointer. so to access member variables use the -> operator instead of the .



remember that when using pointers, a pointer is not the object itself. It is literally a pointer to where the object lives in memory. the -> operator dereferences the pointer so what comes after it is what exists at the memory location held in the pointer.

[EDIT: for an object as small as a vector that 2nd option that you call "the bad way" is probably much more efficient. memory allocations to the heap are slow, a vector is small and so should have no problem fitting on the stack]

lol! , so simple !!
Thanks , that was quick :)

EDIT:

@Loren:
Thanks , it was just a stupid mistake while i was removing the big part of the function.. :)

Hmm...even if your struct class uses operators ?

And just in case you didn't fully get it, TEMP->x is equivalent to (*TEMP).x

Why do you say this? operators are just like any other function, it has nothing to do with whether you allocate statically or dynamically.
