ele1 = gets.chomp
puts "Enter the second element "
ele2 = gets.chomp
puts "Enter the third element "
ele3 = gets.chomp
puts "Enter the fourth element "
ele4 = gets.chomp
# creating array using input elements
arr = Array.[](ele1,ele2,ele3,ele4)
# printing array elements
puts "Array elements are:"
puts arr
Output
Enter the first element
1
Enter the second element
'chandu'
Enter the third element
'flutter'
Enter the fourth element
