When to use the dot operator and when to use the arrow operator in c plus plus?

You use the dot operator when the left side is the name of the object or a reference to an object, and you use the arrow operator when the left side is a pointer to an object.
Example:
struct foobar x, *p= &x;
x.field = p->field;
(&x)->field = (*p).field;

What is use of dot operator in java?
"the dot" connects classes and objects to members. The places where you use it in what I cover are:(1) when you are connecting an object reference variable to a method. The Extending Existing Classes lesson introduces the dot operator for this use, and(2) when you are connecting a class name to one of its static fields. An example of this is the dot between "System" and "out" in the statements we use to print stuff to the console window. System is the name of a class included in every Java implementation. It has an object reference variable that points to a PrintStream object for the console. So, "System.out.println( "text") invokes the println() method of the System.out object.

How what operator is most efficient you plus plus or plus plus you?
Efficiency is the same; the difference is when the "++" is evaluated, before or after other operations. For example: a = b++ // This will first copy b to a, then increment b. a = ++b // This will first increment b, then copy it to a. If you have the "++" operator by itself, it makes no different if you use prefix or postfix. a++ is the same as ++a.
