Booleans
Booleans
Booleans are true
or false
statements. Unlike strings or numbers, booleans store statements of truth: is what I am saying true or false? For example, if I ask, “Are you a robot?”, this question produces a true
or false
result, which we call a Boolean. In this case, since you are not a robot (hopefully!), we would produce false
.
We can also use math operators to create boolean expressions. Here are some examples; however, notice the unusual symbols for “equal to” and “not equal to”:
Operator | Description | Operator | Description |
---|---|---|---|
< | Less than | > | Greater than |
<= | Less than or equal to | >= | Greater than or equal to |
== | Equal to | != | Not equal to |
As usual, use Console.WriteLine
to print out your results:
Console.WriteLine(10 < 8);
Console.WriteLine((3 * 6) == (32 - 14));
Working Together
Try guessing the answers to the following expressions. Use Console.WriteLine
to check your answers.
54 < (10 + 32)
(37 / 5) == 7
"Hello" + "World" == "Hello World"
false == false
