How can I write cool?

Question

I mean, how can I print something on the output, using the while loop and the output appear like someone is writing it right that time.

Answer 1

@visph is right.

The stuff I used to do on Windows though.

for (char i : str)
{
cout << i;
Sleep(30);
}

// something similar, but without enhanced for loops and much more complex with conditional statements evaluating commas, marks and other symbols.

Answer 2

By outputing char by char, with some delay between each (you can even introduce some randomized delay to get a more natural effect than too much regularly char output ^^)

Anyway, you cannot handle this kind of timed effect on code playground due to in/output limitations (except in web project, where in/output are differently handled ;))

Answer 3

I actually wrote something like this in Ruby. It went,

def type(str)
each_char.str do |x|
print x
sleep(0.9)
end
end

type "hello"
