> Array is a collection of values of similar data type.
> An array can be declared as follows
> DataType ArrayName[n]; n - number of elements
eg : int a[5];
float salary[500];
char name[15];
> Array elements can be accessed by mentioning the corresponding index position.
> Index for any array, starts from 0 and ends with n-1
For example,
int a[5];
Then the five array elements can be refered as
a[0],a[1],a[2],a[3] and a[4].
> At the time of declaration of an array, we can initialize the array as follows DataType ArrayName[n] = {values,....};
> In this case, there is no need of mentioning number of elements of array i.e. n.
> If you don't initialize, array elements will have garbage values. For handling array elements, we can frame loops.
> Arrays are of two types
- Numerical Array
- Character Array
