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.
