I have shared, what is array and the types of array, one dimension, and multi dimension array with examples

2. Array
● An ordered set of similar data items.
● All the data stored in consecutive memory location
in RAM

3. ● Syntax:
data_type variable_name[n];
0 to (n-1) / range of array/ number of
data items/ index/ dimension
Eg
● int a[5];

4. Array Structure

5. Array Structure

6. Initialization of Array
● Compile time
Initialize all specified memory locations
Partial array declaration
Initialization with all zeros
Initialization without size
● Run time

7. Initialize all specified memory locations
● int a[5]={1,2,3,4,5};
● Int a[3]={1,2,3,4,5};
// error
a[0] a[1] a[2] a[3] a[4]

8. Partial array declaration
● int a[5]={1,2,3};
a[0] a[1] a[2] a[3] a[4]

9. Initialization with all zeros
● int a[5]={0};
Initialization without size
 char b[]={‘c’,’o’,’m’,’p’,’u’,’t’,’e’,’r’}

10. Run time
Scanf
Eg
● int a[3];
● Scanf(“%d”, “%d”,”%d”,&a[0],&a[1],&a[2])

13. Types of array
➢ One dimensional
➢ Two dimensional
➢ Multi dimensional

14. Two dimensional
Syntax:
data_type variable_name[row_size][coloumn_size];
Eg.
● int a[3][4];

15. Initialization
int a[2][3] = {0,0,0,1,1,1};
OR
= { {0,0,0}, {2,1,2}}
OR
= {{1,1},
{2}};
[1 1 0
2 0 0]

16. Multi dimensional
● data_type array_name[d1][d2][d3][d4]………[dn];
● Where each d is a dimension, and dn is the size of final
dimension.
Examples:
● int table[5][5][20];
● float arr[5][6][5][6][5];

17. Example 1: int table[5][5][20];
● int represents the array type.
● table is the name of our 3D array.
● Our array can hold 500 integer-type elements. This
number is reached by multiplying the value of each
dimension. In this case: 5x5x20=500.
Example 2: float arr[5][6][5][6][5];
● Array arr is a five-dimensional array.
● It can hold 4500 floating-point elements
(5x6x5x6x5=4500).

18. ● single array can hold thousands of values.
● 3D array is essentially an array of arrays of arrays
● it's an array or collection of 2D arrays, and a 2D
array is an array of 1D array.
●

19. ● To call values from the array
25 located in table 1, row 1, and column 1, hence the
address is arr[1][1][1].
