How to Get Array Length in Ruby ?
Answer
To get the length of an array in Ruby, you can use the length
method.
✐ Examples
1 Length of Integer Array
In this example,
- We create an integer array named
numbers
with some values. - We use the
length
method to get the length of the array and store the returned value inlength
variable. - Finally, we shall print the value in
length
to standard output.
Ruby Program
numbers = [1, 2, 3, 4, 5]
length = numbers.length
puts "Length of array is: #{length}"
Output
Length of array is: 5
2 Length of String Array
In this example,
- We create a string array named
names
with some strings. - We use the
length
method to get the length of the array and store the returned value inlength
variable. - Finally, we shall print the value in
length
to standard output.
Ruby Program
names = ["Alice", "Bob", "Charlie"]
length = names.length
puts "Length of array is: #{length}"
Output
Length of array is: 3
