Extra spaces are trimmed when printing to the console in Arcade,
so you don’t have to worry about the extra spacing that comes at the
end from ||functions:printArray||
.
Problem Set: String Array Manipulation
This section contains a number of selected problems for the String Array Manipulation section.
It is recommended that you review the problems, and complete a few before moving on to the next section.
Problem #1: A Bit Pushy
||arrays:Push||
and ||arrays:pop||
can be used to modify arrays,
so that they store the values you want.
In the snippet below, ||functions:printArray||
is used to print out each
value in an array. Run the code, and notice the format of the output to the console.
Use ||arrays:push||
and ||arrays:pop||
to modify ||variables:input||
,
so that the call to ||functions:printArray||
will output the following:
I like to program in MakeCode Arcade
/**
* Prints all the words in the given array, separated by spaces, to the console
* @param words an array of words to print
*/
function printArray(words: string[]) {
let output: string = "";
for (let i = 0; i < words.length; i++) {
output += words[i] + " ";
}
console.log(output);
}
let input: string[] = ["I", "like", "to", "cook", "dinner"];
// Add your code here
printArray(input);
Problem #2: While You Don’t Say That
You have somehow grown a distaste for the word “that”.
Write a small game that will continue to ||game:ask||
the user for
a string until the user has inputted the word “that”.
When that happens, ||game:splash||
“I don’t like that!” and end the game.
Problem #3: Pretty Printing
Fill in ||functions:printArray||
below as described in the function comment.
Make sure that the output for the three tests match the expected output listed
in the comment on each line.
/**
* Prints all the words in the given array, separated by the given separator, to the console
* @param words an array of words to print
* @param seperator the separator placed in between the different elements of the array
*/
function printArray(words: string[], separator: string) {
// Add your code here
}
// Tests!
printArray(["Simple", "Test"], " "); // Should output `Simple Test`
printArray(["Hi", "I", "am", "me"], "!"); // Should output `Hi!I!am!me`
printArray(["Test", "Code", "Here"], "<>"); // Should output `Test<>Code<>Here`
Problem #4: Chatty Bot
Create a simple “Chatbot”, that will ||game:ask||
the player for a
string with the prompt being a random string from an ||arrays:Array||
you make. Be sure to fill up the ||arrays:Array||
with a number of prompts,
to make the bot interesting!
During the conversation, maintain a “log” in the console, and identify whether the bot or user entered that. For example, this might look like the following transcript:
bot: what is your favorite color?
user: red
bot: how are you?
user: good
bot: what is your favorite color?
