Strings in Flogram

Characters can be used to represent letters or numbers. Strings are a sequence of characters and are one of the most common data types used in programming. In Flogram, strings are represented as arrays of characters, providing compatibility with JavaScript.

Declaring a String

Strings in Flogram can be declared as such:

fn main():
    myString: String = "Hello"
    draw(myString)

Accessing Characters

Strings are effectively just arrays of characters, you can access individual characters using their index, just like you would with an array:

firstChar := myString[0]  # This will get the character 'H' from the string and store it into ‘firstChar’

Concatenating Strings

You can concatenate strings using {} within a string which will expand variables into strings:

fn main():
    greeting := "Hello"
    name := "Flogram user"
    fullGreeting := "{greeting} {name}"  
    # fullGreeting is now equal to "Hello Flogram user"
    draw(fullGreeting)

String Length

You can find the length of a string using the size function, the same way you would with an array:

length := size(myString)

Example Code

Here’s a complete code example that demonstrates the above concepts related to strings. You can run this code in the Flogram IDE.

fn main():
    greeting := "Hello"
    name := "Flogram user"
    fullGreeting := "{greeting} {name}!"
    draw(fullGreeting) # Outputs: Hello Flogram user!
    length := size(fullGreeting)
    draw("Greeting length: {length}") # Outputs: Greeting length: 19

Strings are versatile and essential in any programming language, providing a way to handle text data. In Flogram, strings are treated as arrays of characters, allowing for convenient manipulation and access to individual characters.
