Question

Pointer variables are just memory addresses and can be assigned to one another without regard to type True False A pointer is an address, an address is an integer, but a pointer is not an integer. True False When declaring several porter variables, there must be one pointer declarator* for each pointer variable. True False

Answer 1

23.

Pointer variables are just memory addresses and can be assigned to one another withoutregard to type.-

Ans:- FALSE

Explanation:-

A pointer variable, like everything else in C++ is typed, and that typing isenforced strongly. A pointer variable of typedouble*cannot normally hold apointer value of typeint*for example

24:A pointer is an address, an address is an integer, but a pointer is not an integer.

Ans:- TRUE

Explanation:-

This is not too crazy or far off. Rather, this is an abstraction. The type system inC++ is sufficiently strong that it requires that you not assign pointer values toother types nor other types to pointers (without a cast, but that tells the compileryou know what you are doing, so it lets you.)

25:- When declaring several pointer variables, there must be one pointer declarator * for eachpointer variable

Ans:-TRUE

Explanation:-

• Consider this definition ofp1,p2andp3as pointers todoubles:double *p1, *p2, *p3;
• There must be one*for each pointer variable defined
