Variable Declarations
In SunSed, you can declare a variable using the following syntax:
$variable_name = value;
You can name the variable whatever you like, but it must start with a $ symbol. The value assigned to the variable can be of any type, including integers, floats, strings, arrays, and more.
If you don't want to assign a value to the variable at declaration, you can do so using the following syntax:
$variable_name;
The above will create an empty variable with no value.
Additionally, SunSed has some built-in data types for variables, including:
- Integer — whole numbers with no decimal points (e.g.
10)- Float — numbers with decimal points (e.g.
3.14)- String — text values (
"Hello, world!")- Boolean —
true/false values- Array — ordered lists of values (e.g.
[1, 2, 3])Here's an example of variable declarations in SunSed:
# integer variable
$num = 10
# float variable
$pi = 3.14
# string variable
$name = "John"
# boolean variable
$is_true = true
# array variable
$my_array = [1, 2, 3]
# variable can change value too
$name = "Jane"
Variable Names
Variable names in SunSed can contain letters, numbers, and underscores, and must start with a letter or underscore. They cannot contain spaces or special characters like !, @, #, $, %, etc.
Here are some examples of valid variable names:
And here are some examples of invalid variable names:
$my var (contains a space)$my!var (contains a special character)$1var (starts with a number)It's important to choose descriptive variable names that are easy to understand and remember. Good variable names can make your code more readable and easier to maintain in the long run.
