Short Notes – Ruby Arrays- Insert, Append, length, Index, Removed<\/p>\n

Create a Ruby Array<\/p>\n

[code language=”css”]
\nletters = Array.new
\nletters = []
\nletters = Array.new()
\nletters =
\nletters = Array.new(3) ( Define how many elements you array would be)
\nletters = Array.new(3, ‘me rocks’) (Define each element with default values)
\n[\/code]<\/p>\n

Accessing Elements<\/p>\n

[code language=”css”]
\nletters[0] – accessing First element
\nletters[-1] – Accessing last element
\nletters[-2]
\n[\/code]<\/p>\n

Inserting\/Adding elements<\/p>\n

[code language=”css”]
\nletters = Array.new() OUTPUT = [“a”, “b”, “c”]
\nletters.insert(0, 1) OUTPUT [1, “a”, “b”, “c”, “d”]
\nletters.insert(-1, ‘d’) OUTPUT [1, “a”, “b”, “c”, “d”]
\nletters << ‘e’ OUTPUT [1, “a”, “b”, “c”, “d”, “e”]
\nletters.push(‘f’) OUTPUT [1, “a”, “b”, “c”, “d”, “e”, “f”]
\n[\/code]<\/p>\n

Removing Elements<\/p>\n

[code language=”css”]
\nletters.pop – Remove the last elements
\nletters.delete_at(2) – Delete the element of particular index
