Interactive Input — Learn bubblecode

So far, your programs have worked with values you typed into the code. The ask command lets your program get input from the person running it.

The `ask` command

ask displays a prompt and waits for the user to type something:

ask.bubble

ask "What is your name?" into name
say "Hello," && name & "!"

Click Run, then type your name in the input box and press Enter.

Multiple questions

You can ask as many questions as you need:

multi-ask.bubble

say "Welcome to the bubblecode Greeter!"
say ""
 
ask "What is your name?" into name
ask "Where are you from?" into city
 
say ""
say "Nice to meet you," && name & "!"
say "I hear" && city && "is a great place."

Using input with math

User input comes in as text. Use number() to convert it for math:

calc-input.bubble

ask "Enter a number:" into n
put number(n) into num
 
say num && "doubled is" && (num * 2)
say num && "squared is" && (num * num)

Building a simple quiz

Combine ask with if to make an interactive quiz:

quiz.bubble

put 0 into score
 
ask "What is 5 + 3?" into a1
if a1 is "8" then
say "Correct!"
put score + 1 into score
else
say "Wrong — the answer is 8."
end if
 
ask "What is the capital of France?" into a2
if a2 is "Paris" then
say "Correct!"
put score + 1 into score
else
say "Wrong — it's Paris."
end if
 
say ""
say "You got" && score && "out of 2!"

Exercise
