Lab 1.02 - Using the Interpreter

Part 1

Using the interpreter, type in the expressions below. Copy and paste the output into the output column. If the result is unexpected, note that in the third column.

Section 1

	Input	Output	Did it do something unexpected?
a	5 + 2 * 2
b	2/3
c	2.0 * 1.5
d	(2 + 3) * 10
e	5.0 // 2
f	5.0 % 2

Section 2

	Input	Output	Did it do something unexpected?
a	a
b	'a'

Section 3

	Input	Output	Did it do something unexpected?
a	'a + b'
b	'a' + 'b'

Section 4

	Input	Output	Did it do something unexpected?
a	'a' * 'b'
b	'a' * 2

Part 2

Before going to the IDE

1. For each item, predict the data type of the result and enter into the "String/Integer/Float" column.
2. Next, predict the value of the result for each item and enter into it into the "Prediction of Result" column.

	Expression	String/Integer/Float	Prediction of Result	Interpreter Result
a	10 * 2	integer	20	20
b	.5 * 2
c	10/2
d	10%2
e	2 ** 3
f	(2+5)*3
g	2 + 5 * 3
h	'ab' + '12' + '3'
i	x
j	"ab" + "cd"
k	'abc' * 2
l	'1'*2 + '2' * 3
m	1 * 2 + '3' * 2
n	'A' ** 2
o	'bc' % 2
p	'bc' / 2

Now go to the IDE

Use the interpreter to evaluate the expressions, write down results in the "Interpreter Result" column.
