CPModule 3 Making Decisions

When do you use an else statement?

• To tell what will happen when an if-statement is false

• To end an IF statement

• To handle string values

• To Input a variable

Consider the following code:

word = "kangaroo"

if (word == "KANGAROO"):

print ("TRUE")

else:

print ("FALSE")

What is output?

Consider the following code:

if (90 < = x <= 100)

it should be rewritten as:

• if (90 < = x <= 100):

• if (90 < = x and <= 100):

• if (90 < = x and x <= 100):

• Nothing, the if statement is correct

Which of the following is NOT true about all algorithms?

• All algorithms can only do number calculations

• All algorithms have clear instructions

• All algorithms stop in a finite amount of time

• All algorithms have an order

The following code could be rewritten using:

if (x > 12):

if (x < 34):

• not

• or

• and

Write the code to test if num1 and num2 are NOT the same.

• if (num1 != num2 )

• if (num1 == num2 )

• if (num1 = num2)

• if (num1 < num2 )

Both conditions must be true

• and

• !=

• or

• ==

• not

One or both conditions must be true

• >

• !=

• ==

• and

• or

Not equal to

• <

• or

• !=

• and

• ==

Less than or equal to

• <

• <=

• not

• or

• >=
