1.1 Arrays in Data Structure | Declaration,Initialization, Memory representation
Lectures CS IT
data is to be represented in memory or you can see the memory
representation of an array. you will see what is the need of ferry
what does any types of ferry how areas can be declared how arrays
can be. be. declared and how data can be stored in memory. you
will see how the state has to be stored first of all this decimal
number 5 has to. be converted into binary it 's binary number sorry
that is in 32 bits. faerie explains what is need of faerie and how to
deal with it. faerie: we have to process large amount of return that is
why the concept of array came now you will modify this declaration
such that under one variable name we can store roll numbers of all
60 students that is what array now how you can do this. declaration
of arrays languagespecific i am considering the syntax in c language
in python maybe it 's different in pascal in you can say that foreign
language the declaration syntax would be a little bit different so it is
language specific fine now this is what the array declaration is.
The data is stored in consecutive locations or continuous locations
one after another. The index starts from zero, but can also start
from one. The data is stored in binary form and the address of the
data is calculated in hexadecimal form.
At runtime, you can initialize the array using loops, maybe for loop
while you do loup and some predefined function standard functions
that is scanner. In next video, I'm going to discuss it how the data is
to be taken from the user how the data is to be stored in the array.
In next video, we are going to discuss how the data is to be inserted
how the arrays are to be traversed different types of operations on
1d array first of all with their time taken. After that, we will discuss
what is 2d array as well as how 2d arrays are to be accessed from
the air fine.
