What is Array in c

What is an Array in C? A Comprehensive Guide

In C programming language, an array is a collection of elements of the same data type that are stored in contiguous memory locations. The elements in an array can be accessed using an index or a subscript, which starts from zero. Arrays in C are useful for storing and manipulating large sets of data efficiently.

In C, arrays can be declared statically or dynamically. Static arrays have a fixed size that is specified at compile time, while dynamic arrays can be resized during runtime using memory allocation functions such as malloc() and calloc().

syntax: Data_type variable name[ele];

Here's an example of a static array declaration in C:

int myArray[5]; // Declares an integer array with five elements

And here's an example of a dynamic array declaration in C:

int *myArray; // Declares a pointer to an integer array
myArray = (int *)malloc(5 * sizeof(int)); // Allocates memory for an integer array with five elements

In both cases, the array can be accessed using the index notation, like this:

myArray[0] = 10; // Assigns 10 to the first element of the array
int x = myArray[2]; // Retrieves the value of the third element of the array
