Complete the random generator code for the following pseudocode that simulates rolling a die 10 times by generating and displaying 10 random integers, with a range of 1 to 6. (Note, this question has 2 parts; you must answer each part correctly to receive full marks. Enter only the numbers in the space provided.) Declare Die, X As Integer For (X = 1; X <= 10; X++) Set Die = Floor(Random()* )+ Write "Die face: " + Die End For

All of these can be nested in a For loop

What does the following program segment do? Declare Count As Integer Declare Sum As Integer Set Sum = 0 For (Count = 1; Count < 50; Count++) Set Sum = Sum + Count End For It sums all the integers from 1 through 49 It sums all the integers from 0 through 50 It sums all the integers from 1 through 50 It does nothing since there is no Write statement

It sums all the integers from 1 through 49

If Number is an integer value, what would be displayed as a result of the following assignment? (Note: if there are any spaces, it is assumed to be one space.) Set Number = Length_Of(" ") Write Number

False

If Number = 3.5, what would be the result of the following conditional statement? True or false? Floor(Number/2) == Number/2 True False

False

The _____________ function takes a string or a string variable inside the parentheses and returns the number of characters in that string.

Length_Of()

If a counter named MyCount in a For loop has the value of 5 on the first pass, 10 on the second pass, 15 on the third pass, and so on, the increment would be written as __________. (Do not include spaces in your answer).

MyCount + 5

The starting value of an algorithm used to generate a range of numbers is called the _________.

Seed

What is wrong with the following pseudocode? Declare Count As Integer Declare TheNumber As Integer Set TheNumber = 12 For (Count = 10; Count>TheNumber; Count--) Write TheNumber + Count End For The loop will never be entered since the initial value of Count is less than the test condition The limit condition in a For loop cannot be a variable A counter must start at 0 or 1 The loop will never end since the test condition will never be met

The loop will never end since the test condition will never be met

If one For loop is nested within another, then the counter variables for the two loops should be _________.

different
