1.1 Arrays in Data Structure | Declaration, Initialization, Memory representation
Jenny's 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.

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.
1.3 Array Operations | Deletion from Array | Explanation with Code | Data Structure
Jenny's Lectures CS IT
I will discuss the deletion operation using the example I used in a previous video. Understanding
how to delete data from a specific position will also make it easier to delete data from the
beginning or end of the array. I declared an array of size 50 in the previous code, and the
memory manager allocated 200 bytes of memory for this array. One variable, size, is used to
determine the maximum size of the array. If the user wants to insert only 10 or 5 elements, for
example, I will ask them how much size they want for the array, and this will allocate an
additional 4 bytes of memory. The user will then enter the elements of the array, which will be
initialized at runtime. To delete data from the array, I will ask the user from which position they
want to delete the data. For example, if they want to delete data from position 2, I will shift the
