Question
hello there..
i really need help through this assighnment.
(Create a new file on your Neocities page called whilePractice.html
Create a new button for each of the following problems:
1. Prompt the user for a number. Flip a coin (use the random number generator that can only generate two numbers) that many times. When finished, report to the user how many heads and how many tails you ended up with.
2. Write a loop that continues to prompt the user for a number until they enter a negative number. When the loop ends, report how many numbers were entered (do not count the -1) and what those numbers added up to (do not count the -1).
3. Create a function that plays a guessing game with the user. The computer should choose a random number between 0 and 1000 and allow the user to guess for it until they get it correct. Give the user hints. If their number is too high, print "Too High". If their guess is too low, print "Too low". When they get the answer correct, report that it is correct and tell them how many guesses it took.)
