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.
