Array Operations
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 :
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 :
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
