If & else
Pikt handles conditions the traditional way via if
/ else
/ else if
statements. Syntax:
if <condition> <block>
else if <condition> <block>
else <block>
Where <condition>
can be any kind of expression.
If it is a boolean expression, the condition is true
only if the boolean is true
. Otherwise the condition is true
if the given expression is not null
, but we will learn about nullable values later.
<block>
contains the code to be executed if the condition is satisfied.
It can be either a single action, such as a print, a function call or a variable update, or a more complex block. In that case, it has to be surrounded by lambda.open
and lambda.close
, as shown in the for-each guide.
Pseudocode:
if (true) {
print("OK")
} else {
print("NO")
}
Pikt (remember that true
is represented by bool.true
):
But, since print
is a single action, we can remove lambda.open
and lambda.close
in order to make it look more compact:
Pikt offers a standard set of logical and relational operators to build boolean expressions:
-
op.and
(&&
) -
op.or
(||
) -
op.equality
(==
) -
op.inequality
(!=
) -
op.greater
(>
) -
op.greater_or_equals
(>=
) -
op.less
(<
) -
op.less_or_equals
(>=
)
Like many programming languages, operators must be put between two values.
Pseudocode:
var my_var = 1
if (my_var == 1) {
print("OK")
} else if (true && false) {
print("NO")
}
Pikt (remember that false
is represented by bool.false
):
