Question

The advantage a linked list has over an array is: ______________________________

		A linked list takes less memory space than an array for the same amount of data.
		Where data stored are ordered, insertion is faster in a linked-list than in an array because no movement of smaller data items is needed in linked lists.
		Finding an element is faster in a linked-list than in an array.
		A linked-list stores more accurate data than an array.

Which of these in NOT one of the tools for documenting a solution to a problem before the program is written? _________________

		flowchart
		internal documentation
		pseudocode
		UML

The security problem of C-style string copying such using strcpy is ___________________

		only C-style string copy can be used by virus writers.
		an attacker can control the contents, such as putting a virus in your program, by providing a string with more than the allocated memory.
		C-style string copy corrupts the copied data.
		C-style string copy has no security issues.

Answer 1

A linked list takes less memory space than an array for the same amount of data.If the no.of values in array is less than it's actual size then array size is wasted but in linked list it will prevent.(Option A)

pseudocode will not be written before itself .By using the documentation we will develop the code.(Option C)

It corrupts the copied data because it will not specify the original size what if the data is already present in that position,so,it overwrites it.(Option c)
