Basically it's a list.
Instead of typing x0, x1, x2, x3, x4... x99, an array lets you just type x[100]. Then to use each variable you just type x[number] and use it as normal. Arrays are so useful because you can iterate, or repeat, over them easily. You could define an array, then define an integer i. They you could make a loop in your program that increases each x value by 2. Just make it so I gets bigger each run of the loop and type this:
x[i] = x[i] + 2
A Note: if you define the array x to have 100 values, than it will go from 0 to 99, not 1 to 100.
There are also more advanced arrays that can get bigger as you need them to. They will grow without you thinking about it. You can also add data in the middle, and have all the data after it shifted one place. Or you could delete a piece of data from the middle and have all data after it shifted back one place. These arrays are generally called mutable (which means changeable) arrays. Normal arrays are called immutable arrays.

Application of array in data structure?
That rather depends on the underlying type. For any given type T, an array of type T is user-defined if T is user-defined, otherwise it is built-in. For example: #include<string> // required to use std::string std::string s[42]; // user-defined array int i[42]; // built-in array Here, s is a user-defined array because std::string is a user-defined type, whereas i is a built-in array because int is a built-in type.
What is array Explain with syntax?
an array is a collection of the same data type.
What is the midpoint in a data array?

What is string array?
A string array is an array whose contents are strings.An array is when you use a single variable names to store different data items. The data items are distinguished by a number (sometimes by more than one).A string is a data type used to store texts. It may contain letters, digits, or other symbols.A string array is an array whose contents are strings.An array is when you use a single variable names to store different data items.

Can you store non primitive data type in the array list?
Yes you can store non primitive data type variables in an array. String is a non primitive data type. You can declare a string array as: String a[]=new String[10];
