What is an Array?
Asked by M Surendra Last Modified
Answer 
Noorul Ain Arshi
IT Professional Trainer with 4 years of experience in Computer and IT Engineering .
An Array contains multiple data of the same data type.
i.e. int ar[5]; means variable ar can contain five values whose data type will be of integer type.
To access the values of the above-initialised array, you need to write like this
ar[0]
ar[1]
ar[2]
ar[3]
ar[4]
Note: index of the array always begins from 0
In general, Array is a collection of values. But having the same data type of benefits is not identical in all languages.
In Java, c, c++ etc languages it is collection of same data types.
In a language like JavaScript, it is not strict about the data type. I mean one array can have numbers, strings, objects in it.
