Turing/Answers To Programming Language Exercises
Lecture 1[edit | edit source]
Introduction to Turing Programming Language
1. Make a program that outputs a string on one line and then another one on the next.
put "Hello, World" put "This is another line"
2. Make the second example print out both strings on the same line, without removing the second put. Note: You will have to do some research on this.
put "This part ends, ".. %This command is very useful for get statements after text put "But this one starts immediately after."

Variables and Types in Turing
1.Make a program that has the user input their name and then prints it out (Hint: to print a variable, you cannot put quotation marks around it)
var name : string put "Please enter your name here: ".. get name put "Your name is ".. put name
2.Make a variable that stores 10 names in an array, and if you want, prints them out. You will learn a more efficient way of doing this next lesson.
var names : array 1..10 of string get names (1) get names (2) get names (3) get names (4) get names (5) get names (6) get names (7) get names (8) get names (9) get names (10) put names (1) put names (2) put names (3) put names (4) put names (5) put names (6) put names (7) put names (8) put names (9) put names (10)

Control Structures and Logical Expressions in Turing
1.Make the user input a user name and password. (Hint: If statement)
var username, password : string put "What is your username?" .. get username put "What is your password?" .. get password if (username = "user1") and (password = "drowssap") then put "Welcome, username else put "Incorrect password or username" end if
2.Make the program give the user as many tries as they want, or if you want a challenge, 5 tries (Hint: Loop)
var username, password : string var tries : int %Anything in this code with a '%' after it is for the challenge loop put "What is your username?" .. get username put "What is your password?" .. get password if (username = "user1") and (password = "drowssap") then put "Welcome, username else put "Incorrect password or username" end if tries += 1 % exit when tries = 5 % end loop
3.Re-do exercise 2 (input 10 values from an array) from the last one, with for statements
var names : array 1..10 of int for i : 1..10 get name (i) end for for i : 1..10 put name (i) end for
Lecture 4[edit | edit source]
Functions and Subroutines 1.Make a function that calculates the number times 6, plus 3 divided by 2
var iput : int get iput function math (x : int) : real result (x * 6 + 3) / 2 end math put math (iput)
2.Make a procedure that puts 'hi' and then one that gets a string. Then call on them at random. (Hint: Use Rand.Int: Rand.Int (1,5) randomly outputs a number between 1 and 5.)
var iput : string var which : int procedure hi put hi end hi prodedure getiput get iput end getiput loop which := Rand.Int (1,2) if (which = 1) then hi elsif (which = 2) then getiput end if end loop
