Which among the statements below is/are true? *

2 points

An array list requires a form of special marking which caused the linear cost to inserting and deleting elements.

Deleting the first element in the linked list is done in constant time.

A linked list has a fixed size memory allocation for each element.

Required

Which among the statements below are true about fwrite()? *

2 points

The fwrite() function always requires the address of variable containing the data to be written to the file.

The value returned by fwrite() will be greater than or equal to the value in its third parameter.

Using fwrite() would require any of "w", "wb", "w+" or "w+b" in its parameter list to make a legal function call.

Required

Which of these statements about linked list is false? *

2 points

Elements in the array list are accessed sequentially.

Nodes in the linked list are dynamically allocated and deallocated.

A self-referenced structure is always necessary in a linked list.

Linked list pointer variable is stored in the execution stack, and not in the heap memory.

Random access of elements cannot be performed in a linked list.

Elements are stored at contiguous memory locations.

Which of the following is true? *

2 points

Runtime error in the declaration and initialization.

Compiler error in the declaration and initialization.

Compiler error in the data structure definition.

No compiler and runtime error.

Which of these statements about array implementation of ADT list is true? *

2 points

Elements in the array list are accessed sequentially but not randomly.

Random access of elements cannot be performed in the array list.

The physical order of elements is not the same as the logical order of the elements.

The number of elements that can be stored in the list is infinite.

The memory allocation for an empty list is the same as a non-empty list.

Elements are not stored in contiguous memory locations.

Which of these statements is true about linked list and array list? *

2 points

The time to delete the first element of the array list is shorter compared to linked list.

Elements for array list and linked list are stored in contiguous memory locations.

The time to add an element at the end list is the same for linked list and array list.

The time to update the first element of the list is the same for linked list and array list.

Array list and linked list can be accessed sequentially and randomly.

Required

Given the code snippet, which of the following is true about the code snippet? *

2 points

None of the choices

Memory leak or garbage in the heap is created when c is made to point to b

free(a) is a runtime error because heap memory was created through c

sizeof(c) > sizeof(b)

free(c) will free the dynamically allocated space
