Just tell me the answers. Do not give me long reasons.

A reference type variable is similar to a pointer except for a fundamental difference of: a) it can utilize the 'nil' value in special ways. b) it can only access memory that is dynamically allocated in the heap. c) it refers to only a memory location. d) it refers to only an object or value in memory. Nan Listen to this page 'alence is a) Where entire structures of the two types must be compared. b) Where it is difficult to implement and less restrictive. c) When two variables have same type if their types use the same structures. d) When two variables are in the same declaration or use the same type name A is a heterogeneous collection of data elements where the individual eler ied and accessed through offsets (column number) from the beginning of the structure. a) tuple b) list c) struct d) record What are two advantages for decimal data type? (Chose two) Select 2 correct answer(s) Listen to this page a) Stores a tixed number of digits with an implied decimal point in a fixed position. b) Ability to precisely store non-integer values. c) Operations with this data type are only done in hardware, never in simulated software, thus requiring expensive computing machines. d) Are stored in very small memory, much smaller than binary representations. What is strong typed in a programming language? a) It is considered to be of low value to a programming language. b) Run-time type errors are detected, but the program uses indirect type conversion to overcome the errors. c) All type errors and any misuse of variables are always detected at compiletime or run-time. d) All coercion rules for a programming language are ignored with strong typing
