Language: LISP (1).......

Lisp (LISt Processing) is a very old language (1958).
; for line commenting
script extension is .lisp
CLisp is common lisp.
terpri function outputs a newline to output-stream. (TERminate PRInt line)

String printing
(write-line "Autumn leaves make me happy")
(write-line "I love picking them.")
(write-line "His authored a book titled \"Eternal peace.\"")

Autumn leaves make me happy                                                                     

I love picking them                                                                             

His authored a book titled "Eternal peace."

---------------------
Case-sensitive comparison
(write (string= "hi" "Hi"))
(terpri)
(write (string> "hi" "Hi"))
(terpri)

NIL                                                                                                                           

0

---------------------
String case conversion
(write-line (string-upcase "winter is almost here."))
(write-line (string-capitalize "sun sets very early."))

WINTER IS ALMOST HERE.                                                                

Sun Sets Very Early. 

(write-line (string-downcase "PLUMERIA FLOWER IS VERY FRAGRANT."))
(write-line (string-capitalize "seaweeds are algae."))

plumeria flower is very fragrant.                                                     

Seaweeds Are Algae.

---------------------
Stripping the spaces
(write-line (string-trim "   Its a cold night   "))
(write-line (string-left-trim "       Owls are hooting."))
(write-line (string-right-trim "Bats are flying    "))
(write-line (string-trim " "I"    I an scared."))

---------------------
Finding length of string
(write (length "Chaparral flora"))
(terpri)
; pull all characters except the number 1 character
(write-line (subseq "Chaparral" 1))
; pull the character only at index 1
(write (char "Chaparral" 1))

15                                                                                                              

haparral                                                                                                        

#\h                                                                                                             

---------------------
Sorting the strings (ascending, descending order)
(write (sort (vector "milk" "egg" "fruits" "vegetables") #'string<))
(terpri)
(write (sort (vector "milk" "egg" "fruits" "vegetables") #'string<))
(terpri)
#("egg" "fruits" "milk" "vegetables") 
#("vegetables" "milk" "fruits" "egg") 
---------------------
Joining strings (order of strings vary based on < or > symbol used).
(write(merge'vector(vector "tulip" "hibiscus")(vector "rose" "jasmine")#'string<))
(terpri)
(write(merge'vector(vector "tulip" "hibiscus")(vector "rose" "jasmine")#'string>))

#("rose" "jasmine" "tulip" "hibiscus")                                                              

#("tulip" "rose" "jasmine" "hibiscus")  

---------------------
Reversing a string
(write-line (reverse "Calley pear blooms are spectacular."))

Joining strings
(write-line (concatenate 'string "I like hiking." "Nature fascinates me."))
