Deck 9: Strings and Arrays Assessment

Question 1

Binary search uses a divide and conquer strategy.

Answer 1

True

Question 2

The CMPSW instruction uses memory pointed to by EDI as the source operand.

Answer 2

False

Question 3

array[EDX+ESI] is an example of a base-index-displacement operand.

Answer 3

True

Question 4

The CLD instruction causes the ESI and EDI registers to be increased in value by the MOVSB instruction.

Question 5

The Str_compare procedure returns no value in the EAX register.Instead,it sets the Carry and Zero flags.

Question 6

The REPNZ CMPSB instruction pair will execute as long as the byte pointed to by ESI is not equal to the byte pointed to by EDI.

Question 7

The REPNE prefix repeats an instruction while the Zero flag is set,and ECX is greater than zero.

Question 8

The LODSD instruction loads a doubleword from the memory location addressed by ESI.

Question 9

The Str_trim procedure has a second parameter that holds the character to be trimmed from the end of the string.

Question 10

The EDX and ECX registers can be combined in a based-indexed operand.

Question 11

The MOVSW instruction copies a word from the location addressed by ESI to the location addressed by EDI.

Question 12

In 64-bit mode,operands that use register indexes must use 64-bit registers.You can use both base-index operands and base-index-displacement operands.

Question 13

When calling Str_compare in the Irvine32 library,you can pass arguments to it in 32-bit registers.

Question 14

On the first pass through an array of N items,the inner loop of a bubble sort executes N  1 times.

Question 15

If an O(n2)sorting algorithm requires 0.2 seconds to sort an array of 1,000 elements,it will require 200 seconds to sort 10,000 elements.
