Answer 1

Arrays a kind of data structure to store multiple homogenous elements. Arrays are mutable i.e we can modify after creating an array.

Declaring Arrays

To declare an array in C, you have to specify the data type of the elements and the number of elements can be stored in an array as follows −

type arrayName [ arraySize ];

Example:

double balance[10];

Initializing Arrays

You can initialize an array in C in a single statement as shown below −

double balance[5] = {250.0, 2.0, 3.4, 17.0, 450.0};

double salary = balance[9];
