C++ Introduction to arrays
An array is a group of identically typed elements that are kept in a single block of memory in C++. An index, which denotes the location of the element in the array, can be used to access the items in an array. The initial element’s index is 0, and it rises to the array size minus one for all subsequent elements.
Data that can be represented as a group of identical things can be stored and managed using arrays. An array can be used to store a list of characters, an array of strings, or an array of integers.
Syntax of declaring array:
type name[size];where size is the number of elements in the array, name is its name, and type is the data type of the array’s contents. Here is an illustration of declaring an integer array:
Example of declaring array:
int numbers[5];This indicates the existence of the 5-int numbers array.
Curly braces {} can be used to initialize an array with values as well.
Example:
int numbers[5] = {1, 2, 3, 4, 5};The numbers array is initialised with the values 1, 2, 3, 4, and 5.
A crucial data structure in programming, arrays are widely employed in a variety of applications.
