Syntax: length(A::AbstractArray) Parameters: A: Specified array Returns: It returns the number of elements present in the specified array. Example 1: # Julia program to illustrate # the use of Array length() method # Finding the number of elements present in # the specified 1D array A. A = [5, 10, 15, 20] println(length(A)) # Finding the number of elements present in # the specified 2D array B of size 2 * 2 B = [5 10; 15 20] println(length(B)) # Finding the number of elements present in # the specified 3D array C of size 2 * 2*2 C = cat([1 2; 3 4], [5 6; 7 8], [9 10; 11 12], dims = 3) println(length(C)) Output: Example 2: # Julia program to illustrate # the use of Array length() method # Finding the number of elements present in # the specified 1D array A. A = [1, 2, 3]; println(length(A)) # Finding the number of elements present in # the specified 2D array B of size 2 * 2 B = [2 4; 6 8; 10 12]; println(length(B)) # Finding the number of elements present in # the specified 3D array C of size 2 * 2*2 C = cat([1 2; 3 4], [5 6; 7 8], [9 10; 11 12], [13 14; 15 16], dims = 4); println(length(C)) Output: Last Updated : 26 Mar, 2020 Like Article Save Article Previous Formatting of Strings in Julia Next Check if a string contains a non-ASCII value in Julia - ascii() Method Share your thoughts in the comments Add Your Comment Please Login to comment...
