Appending Array in Godot
An array is a collection of one or more values of the same type. Each value is called an element of the array. The components of the array share the same variable name, but each part has its unique index number (also known as a subscript).
An array can be of any type, for example, int, float, char, etc.
Always remember arrays always start from their index value, and the index of the array is begun from 0 to n-1.
Suppose we want to access the 5th element of the array, then we will help us 4th element because arrays start from 0, and the array is always stored in contiguous memory locations. The number of elements and types of array identified by the subscript of array elements. The various types of Array that are provided by c as follows:-
Single dimensional Array
A dimensional is used representing the elements of the array
The  is used for dimensional or the subscript of the array that is generally used for declaring the elements of the array.
For Accessing the Element from the collection, we can use the Subscript of the Array like this
This will set the value of the 4th element of an array
So there is only the single bracket then it called the Single Dimensional Array
This is also called as the Single Dimensional array
Two Dimensional Arrays or matrix
The two-dimensional array is used for representing the elements of the array in the form of the rows and columns, and these are used for representing the matrix A two-dimensional array uses the two subscripts for declaring the elements of the Array Like this int a  
Multidimensional or Three Dimensional Array:
The multidimensional array is used for representing the total number of tables of matrix A three-dimensional array is used when we want to make the two or more tables of the matrix elements for declaring the array element we can use the way like this
Int a 
This first 3 represents the total number of Tables, and the second 3 represents the total number of rows in each table, and the third 3 represents the total number of columns in the tables.
So this makes the 3 tables having the three rows and the three columns the primary and essential thing about the array that the elements are always stored in the contiguous in the memory of the computer.
Character Array of String
As an integer, the character is also in the Array. The array of characters is called the strings; they are generally used for representing the strings always remember that a string is terminated with the \o or null character.
There is the built-in string operation; the C language in the string provides those.h header file like
Open Godot Engine, then click on the script.
Updated coded part:
If we press any function with the ctrl button, then we see the description and type of function like below we click on size () then the following description will open.
Could you scroll down to see more about it?
Then we run the code the output will be like this:
After this question and answers, the story will be generated below:
Now we can change some DisplayText also as our wish as we do: And at the end, we should add a Plus (+) sign to add the display text into it.
These lines are the added lines.
Updated code is:
Output after adding lines:
And here the story is ready.
