Operations on Arrays in Data Structure
In this blog post, we will be discussing the various operations that can be
performed on 1D arrays in data structures. We have already covered the
fundamentals of arrays, including why they are needed, how to declare
them, and their memory representation in a previous post. Today, we will
focus on how to traverse an array, how to insert data into an array, and the
three types of insertion (at the beginning, at the end, or at a specific
position). The most important operations we will cover are array traversal,
insertion, deletion, sorting, and searching for a particular key.
Traversal and Insertion with Code Examples
We will start by discussing how to traverse an array and insert data into an
array, with the help of code examples. We will also provide code for array
deletion.
Array Size and Memory Allocation
Before we dive into the code, it's important to understand that the size of
an array is fixed at compile time and cannot be changed at runtime.
Additionally, arrays do not have any bounds checking property at runtime,
so it is the programmer's responsibility to check the boundaries of the
array in the program. For example, if we declare an array of size 50, 200
bytes of memory would be allocated by the memory manager. The base
address is 100, so 100 to 299 bytes should be allocated to this array.
Reading and Writing Data
Now, let's discuss how to read and write data in an array.
The scanf function is used to take input from the user, and
the printf function is used to print something on the output screen.
When using scanf , we write %d for integers. We use a for loop to
iterate over the array, and the value starts from 0 till the size minus one
(i++).
