2. True/False: Procedural a.bstraction says that a typed procedure's parameter values are abstract, hiding their implementation details from the function being invoked. 3. True/Fa.lse: Smalltalk does not use any static type checking, whereas C++ can issue many type-level errors at compile time. 4. True/False: In general, to say type A is a subtype of B is exactly to say A inherits from B. 5. True/False: If an expression in strict binary prefix notation contains N operators, it must contain 2N literal values to be well formed (because all operators are binary). 6. True/False: An abstract data type (ADT) consists of a type together with an interface-a. specified set of operations. 7. True/False: Dynamic lookup (also called dynamic dispatch) is a main reason for Java's greater overhead at function calls compared to C++. 8. True/False: If a typed value can be used in any place where another type is required, the first type is a subtype of the second. 9. True/False: In Smalltalk, a private method can only be accessed by code in that class or one that inherits from it. In C++ this is called a protected method. 10. True/False: In C++ a class can inherit from multiple objects at once, while in Java multiple inheritance (from parent classes) is disallowed. 11. True/False: In the scope of a. C++ declaration int** x;x is a reference to an integer, while given declaration int* x;,x is a pointer to an integer. 12. True/False: In C++, a method operator [] need not implement indexing of a container just
