1. Arrays in Data Structure | Declaration, Initialization, Memory
representation
How data is represented in memory, and the
need for arrays? Faerie explains the need for
arrays as we often have to process large amounts
of data, and arrays allow us to store multiple
values under one variable name. We'll cover how
arrays can be declared and how data can be
stored in memory. The declaration of arrays is
language-specific, and in this video, we'll consider
the syntax in the C language. The elements of the
array are stored in consecutive or continuous
locations, with their index starting from zero. The
size of the array cannot be changed at runtime.
We'll discuss how data is stored in memory, with
the binary form of the data being converted and
then stored. The formula to calculate the address
of an element is the base address plus the index
value multiplied by the size of the data type. We'll
cover how to initialize the array at runtime using
loops or predefined functions, and how to take
data from the user and store it in an array.
