Arrays in Data Structure | Declaration,
Initialization, Memory representation
Jenny's Lectures CS IT
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.
