Arrays in Data structure In this video, 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.
Array Operations
In this video I am going to talk about various operations performed on arrays in data
structure on 1d arrays specifically. I have already discussed the fundamentals of arrays what
is need of Faerie array declaration in acid ization of array memory representation of air in the
previous video so if you check out that video then I 'll provide you the link in the description
box you can check out there. We are going to write down the code for this. something like
this I have already discussed in the previous video this concept and detail fine. I 'm going to
ask from the user what elements the user wants in the area how to populate the area at
runtime. We will just write header files and all I think you can write that thing. Ask from the
user that how many data the user want to insert in this area what is the actual size of the
array this is the maximum size fine. If user will give something some input that is some
integer value then obviously that value should be stored in memory and how values to be
stored using variable so you have to declare one another variable.
We will discuss how data is to be inserted in the air at specific position. If you get how data
can be inserted at a specific position then you can easily modify the code for inserting the
data at the beginning and at the end of theory fine so now we will see how to. We are using
one more variable that is i so you have to declare this variable. There is no upper bound
checking concept of areas in areas in C like this if you take hair in a is equal to 50 fine.
Memory man is it has has allocated to how many bytes two hundred bytes for storing 50
elements. If you enter the size 51 or you can say 60 then user can insert 60 values also but
that is not actually correct. We all we want all the previous element as well as we want some
extra element that you want to insert so you can not do directly this so another approach is
what you can shift these elements to the right side. From variable to start the loop we are
going to start from here from the last element of there you can say from size minus 1.
of bounds checking of arrays in c so programmer has to write down the code itself for the
checking of the boundaries in c. programmer must write down a for loop for the swapping of
arrays. Programmer writes down code that checks the boundaries of an array in c code. Just
write down a for loop in for loop you will start from 0 to the size fine and you simply write
printf percentage D and a of I and these all values would be printed this is how we are going
to insert the data at specific position fine. After inserting this number array size becomes
what 6 so now size becomes size plus plus plus right now finally you will print this area how
you can print it. How you will insert simply you just enter the data you want to insert simply.
No need to ask the position no need to do this swapping and all fine simply will write a off
