Question 5

What is a dangling pointer?

Accepted Answer

A pointer that contains the address of a dynamic variable

Answer

A pointer that points to the first element of an array

Answer

A pointer that contains an invalid memory address

Answer

A pointer that points to a variable outside its scope

Question 6

Question 9

What is the primary difference between arrays and records?

Accepted Answer

Array elements must be of the same type, while record fields can be of different types

Answer

Arrays can have varying lengths, while records have fixed lengths

Answer

Arrays are stored in contiguous memory, while records are not
