DECLARATION OF ARRAY
Like a regular variable, an array must be declared before it is used. A typical declaration for an array in Visual C istype name elements type is a valid type (like int, float...) name is a valid identifier elements field (which is always enclosed in square brackets ), specifies how many of these elements the array has to contain

include ltiostreamgt using namespace std int
main() // declare an integer array of size
5 int arr5 // initialize the array
with some values arr0 10 arr1
20 arr2 30 arr3 40 arr4
50 // print the values of the array
for (int i 0 i lt 5 i) cout ltlt
"arr" ltlt i ltlt " " ltlt arri ltlt endl
return 0

DEFINITION
A one dimensional array is one in which one subscript /indices specification is needed to specify a particular element of array

DECLARATION
Data_type array_name size of array

EXAMPLE
Int num10
1-D ARRAY

include ltiostreamgt using namespace std int
main() const int size 5 // constant size
of the array int arrsize // declaring an
integer array of size 5 // initializing
array elements using a for loop for(int i0
iltsize i) cout ltlt "Enter element " ltlt
i1 ltlt " " cin gtgt arri //
printing array elements using a for loop cout
ltlt "\nArray elements are " for(int i0
iltsize i) cout ltlt arri ltlt " "
return 0

Enter element 1 10 Enter element 2 20 Enter
element 3 30 Enter element 4 40 Enter element
5 50 Array elements are 10 20 30 40 50

DEFINITION
A 2-d array is an array in which each element is itself an array

Enter element (0, 0) 1 Enter element (0, 1)
2 Enter element (0, 2) 3 Enter element (1, 0)
4 Enter element (1, 1) 5 Enter element (1, 2)
6 Enter element (2, 0) 7 Enter element (2, 1)
8 Enter element (2, 2) 9 Array elements are 1
