An array is an indexed collection of the same type of data elements. It allows for easy retrieval of data through indices that start at 0 and go up to the total number of elements minus one. While arrays provide good performance, they have limitations such as a fixed size and containing only homogenous data members.

1. Array

3. What is an array?
An array is an indexed collection of fixed number of homogenous data
elements.
Index
11 1 21 042233310
0 4 4 5321 6

4. Conclusions
• Total number of elements = 7
• Index starts from = 0
• Index lasts on = total_number – 1;
Since Array is index based so retrieval of data is very easy in array.

5. Limitations of Array
1. Fixed in Size
2. Not good for memory management.
3. Not much ready made methods are available.
4. Homogenous data members.
5. Contains primitive and objects.
6. Performance wise - good
