The intended purpose of the following codes is to set the temp to the value 32.0 if it is not already equal to 32.0. Where is the error? Select the correct code to replace the incorrect code. If NOT temp == 32.0 Then Set temp = 32.0 End If

If NOT (temp == 32.0) Then

Part of the following pseudocode is incompatible with the Java, Python, C, and C++ languages. Select the correct piece of code you would use to replace the incorrect code. Declare Integer num1, num2;set num1= 10;set num2 = 15; If num1 = num2 Then Display "The values are equal." Else Display "The values are NOT equal." End If

If num1 == num 2 Then

The intended purpose of the following codes is to determine whether the value is outside of a specified range. Select the correct line of code to replace the incorrect code. If value < lower AND value > upper Then Display "The value is outside the range." Else Display "The value is within range." End If

If value < lower OR value > upper Then

How many times will the following loop iterate? Set k = 1 While k < = 5 Display k End While

Infinite

Syntax

Find the error in the following pseudocode: Declare Boolean finished = False Declare Integer value, cube While finished != True Display "Enter a value to be cubed." Input value; Set cube = value^3 Display value, " cubed is ". cube End While

The Boolean variable has no way of being modified in the loop.

The programmer intended the following pseudocode to get five sets of two numbers each, calculate the sum of each set, and calculate the sum of all the numbers entered. It will not function as intended, however. Find the error. //This program calculates the sum of five sets of two numbers. Declare Integer number, sum, total Declare Integer sets, numbers Constant Integer MAX_Sets = 5 Constant Integer Max_Numbers = 2 Set sum = 0 Set total = 0 For sets = 1 to MAX_NUMBERS For numbers = 1 to MAX_SETS Display "Enter number ", numbers, " of set ", sets, "." Input number Set sum = sum + number End For Display "The sum of set ", sets, " is ", sum, "." Set total = total + sum Set sum = 0 End for Display "The total of all the sets is ", total, "."

The ranges of the inner loop and outer loop are mismatched.

True

True/False: Most programming languages do not automatically print spaces between multiple items that are displayed on the screen.

True

True/False: Programmers use pseudocode to create 'mock-ups' of programs because they do not have to worry about syntax rules.

True

True/False: The If-Then-Else statement can be used to simplify a complex nested decision structure.

True

True/False: The While loop is known as a pretest loop, which means it tests its condition before performing an iteration.
