Pointer dan Array

Pointer
                Pointer adalah petunjuk suatu variabel (ditandai dengan *).
Contoh pointer:

Output:

Value of Value: 15

Addres of value: 6487620

Value of pointer: 15

Addres of pointer: 6487620

&value menunjukan alamat dari int value(lambang &)

pointer to pointer

pointer hanya dapat menunjuk 1 level dibawahnya(**xx menunjuk *x)

Output:

Value of Value: 15

Addres of value: 6487620

Value of pointer: 15

Addres of pointer: 6487620

Value of *x=250

Value: 250

addres of x:6487608

value of xx: 6487608

**xx = 250

nilai dari value berubah menjadi nilai *p

Array

Array adalah sebuah library yang menyimpan sekumpulan data dengan tipe data yang sama.

Contoh Array:

Output:

Arr1 [0]:10

Arr1 [1]:20

Arr1 [2]:30

Arr1 [3]:40

Arr1 [4]:50

Arr2 [0] [0] = 10

Arr2 [0] [1] = 20

Arr2 [0] [2] = 30

Arr2 [1] [0] = 40

Arr2 [1] [1] = 50

Arr2 [1] [2] = 60

Arr2 [2] [0] = 70

Arr2 [2] [1] = 80

Arr2 [2] [2] = 90

Arr [0] [0] [0] = 100

Arr [0] [0] [1] = 200

Arr [0] [0] [2] = 300

Arr [0] [1] [0] = 400

Arr [0] [1] [1] = 500

Arr [0] [1] [2] = 600

Arr [1] [0] [0] = 700

Arr [1] [0] [1] = 800

Arr [1] [0] [2] = 900

Arr [1] [1] [0] = 1000

Arr [1] [1] [1] = 1100

Arr [1] [1] [2] = 1200

Arr [2] [0] [0] = 1300

Arr [2] [0] [1] = 1400

Arr [2] [0] [2] = 1500

Arr [2] [1] [0] = 1600

Arr [2] [1] [1] = 1700

Arr [2] [1] [2] = 1800
