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++).
