Exam 9: Strings and Arrays Assessment

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

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

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

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

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

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

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.

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

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

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

Binary search uses a divide and conquer strategy.

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.

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.

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

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