Arrays in LISP

Last Updated : 26 May, 2022

LISP, is a list processing, is a programming language widely used in working with data manipulation. LISP allows us to produce single or multiple-dimension arrays using the make-array function. An array can store any LISP object as its elements.

Index Number of the LISP array start from 0 index to the n-th term

The index number of the array starts from 0 to the n-th term.

Attributes:

The setf attribute gives a call to the function.
The aref attribute allows accessing the name of the array and index value.
The my-array attribute is used in creating the cells of the array.
The dotimes attribute allows looping. Looping start from zero to the nth number defined by the user.
The tepri attribute is used to produce a new line,
The initial-content attribute is a sequence of nested structures.

Example 1:

Lisp

// Making a file array
// lisp to print names
(setq myarray (make-array '() 
   :initial-contents 
   '(((Ayush Agarwal) (Piyush Goel)) 
      ((Keshav Kedia) (Gaurav Garg)) 
   ))
) 
(write myarray)
(terpri)

Output:

Example 2:

Lisp

// Lisp code for array
// Making a file array.lisp
// to print number from 10 to 19 .
(write (setf my-array (make-array '(10))))
(terpri)
(setf (aref my-array 0) 10)
(setf (aref my-array 1) 11)
(setf (aref my-array 2) 12)
(setf (aref my-array 3) 13)
(setf (aref my-array 4) 14)
(setf (aref my-array 5) 15)
(setf (aref my-array 6) 16)
(setf (aref my-array 7) 17)
(setf (aref my-array 8) 18)
(setf (aref my-array 9) 19)
(write my-array)

Output:

Example 3:

Lisp

//  Printing a table for 0 and 1 
// using LISP array
(setq a (make-array '(2 11)))
(dotimes (i 2)
   (dotimes (j 11)
      (setf (aref a i j) (list i 'x j '= (* i j)))
   )
)
(dotimes (i 2)
   (dotimes (j 11)
      (print (aref a i j))
   )
)

Output:

Example 4:

Lisp

// Making a file array.
// lisp to print alphabets from A to Z.
(setq myarray (make-array '() 
   :initial-contents 
   '(((a b c) (d e f)) 
      ((g h i) (j k l)) 
      ((m n o) (p q r) (s t u) (v w x y z)) 
   ))
) 
(write myarray)
(terpri)

Characters in LISP

In Lisp data objects of type 'character' are referred to as characters. For representation purposes, we usually denote character objects by preceding a #\ symbol before the character. Any character can be represented by using the #\ symbol before the name of the character. For Example #\a represents
