Thread: -> operator

what does -> mean in a c or c++ program?

if we have a pointer to struct:

Code:

struct x 
{ 
   int a;
   int b;
};

struct x *px;
...
// code assigns valid address to px. 
...

then we can access the contents of the struct this way:

Code:

   (*px).a = 7;
   (*px).b = 9;

But that's quite awkward to write (it gets even worse if you have a struct with pointers to structs in it).
So the language also has a short form of this:

Code:

   px->a = 7;
   px->b = 9l
