1.1 Arrays in Data Structure | Declaration,
Initialization, Memory representation


In this video, we'll discuss 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. In the next video,
we'll discuss how to insert data, traverse arrays, and perform
different operations on 1D arrays. We'll also cover 2D arrays and
how to access their values.
