Swift--Array

One. Arrays

1. Create an empty array

Way One:

var array1 = [Int] ()

Way two:

var array2 = array<string> ()

2. Create a hand with default values

var array3 = [Int].init (count:5 repeatedvalue:10)//5 elements, all 10

var array4 = Array<string>.init (count:5 repeatedvalue: "a")

3. Construct an array with literal literals

var array5:array<int> = [1,2,3,4,5]

4. Merging of two arrays

var = [Array6:array<int>]

var array7:array<int> = [4,5,6]

var array8 = Array6 + array7//Combined two array types need the same

5. Check if the array is empty

Print (Array8.isempty)

6. Number of elements

Print (Array8.count)

7. Add an Element (join later)

var array9:array<int> = [11,22,33]

Array9 + = [44,55,66]

Print (Array9)

8. Insert element (at specified position)

Array9.insert (atindex:0)//AT index 0, insert 10

9. Deleting an element

Array9.removeatindex (0)//delete an element with an index of 0

10. Get an Element

Print (array9[2])

11. Modifying an element (re-assignment)

ARRAY9[2] = 100

12. Modifying an element of an index interval

ARRAY9[3...5] = [1]//index 3,4,5 element full assignment is 1

ARRAY9[3...5] = [three-to-three]//index 3,4,5 elements are

13. Iterating through an array

For I in array9{

Print (i)//printing of each element

}
