loop issue

Question

def get get = gets.chomp end

print " time to add to your array choose 3 items to store "

arr =[] puts arr

while arr.length != 3 puts arr.push(get()) if arr.length == 3 break end end

the goal here is to store three strings or numbers into the array by using the gets method an while loop. Any ideas what i did wrong?

"gets" is already a method in ruby answer = gets.chomp

and you should place everything you need inside your while loop. Try this

# Create an array
arr = []

# Print a line
print "Choose 3 items "

# Start the loop with a "<" and when the array has 3 items in it it will automatically stop
while arr.length < 3
  # Print a line to notify input is needed
  print "> "
  # Get the answer from the user
  answer = gets.chomp
  # Add the answer to the end of the array
  arr.push(answer)
end

# Print out the array so you can see what is in it.
print arr

Hope this helps

# Note that "!=" stands for 'not equal to'
# You should have used "<=" for 'less or equal to'
# An if statement in your code was not entirely necessary
# Your code should have looked like:

arr = []
count = arr.length
while count <= 3
  print "Enter Item"
  item = gets.chomp
  arr.push(item)
  count+=1
end

#Alternatively,

arr = []
count = arr. length
while count <=  2
  print "Enter Item"
  item = gets.chomp
  arr.push(item)
  count+=1
end
