Arrays in Data Structure | Declaration, Initialization, Memory representationJenny's Lectures CS IT
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.
You are also going to have to use the interposition function to insert the data at the beginning of
the area. Finally, you are going to have to use the printf function to print the data at the end of
the area. Delete data from the array.
And finally, we'll discuss the time complexity.value so delete the value at position four so now
the updated area is now 5 and if you want to print this then you can write this value down at the
bottom of the for loop and then you can print this value at the top of the for loop
