1.1 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.
