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 values from position 3 to 4 and reduce the size of
the array by 1. I will start a loop from the position to be deleted to the end of the array and shift the
values to the left. To print the updated array after deletion, I will use a for loop to print each
element of the array. It's important to check the validity of the position entered by the user before
deleting data from the array. If the position is invalid, such as -1 or greater than the size of the array,
I will print "invalid position". If there is no data in the array, it's also an underflow condition and the
