Arrays in Data Structure
Declaration, Initialization, Memory representation
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.
