1.2 Array Operations - Traversal, Insertion | DSA Course
In this Lecture I am going to talk about various operations performed on arrays in data structure on 1d arr
ays specifically. I have already discussed the fundamentals of arrays what is need of Faerie array declara
tion in acid ization of array memory representation of air in the previous video so if you check out that vide
o 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 detai
l fine. I ’m going to ask from the user what elements the user wants in the area how to populate the area a
t 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 inserte
d at a specific position then you can easily modify the code for inserting the data at the beginning and at t
he end of theory fine so now we will see how to. We are using one more variable that is i so you have to d
eclare 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 tha
t is not actually correct. We all we want all the previous element as well as we want some extra element t
hat you want to insert so you can not do directly this so another approach is what you can shift these ele
ments to the right side. From variable to start the loop we are going to start from here from the last eleme
nt 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 d
own code that checks the boundaries of an array in c code. Just write down a for loop in for loop you will s
tart from 0 to the size fine and you simply write printf percentage D and a of I and these all values would b
e printed this is how we are going to insert the data at specific position fine. After inserting this number arr
ay size becomes what 6 so now size becomes size plus plus plus right now finally you will print this area h
ow you can print it. How you will insert simply you just enter the data you want to insert simply. No need t
o ask the position no need to do this swapping and all fine simply will write a off here here means you can
say that size a of size size size is 5 5 so here also you can insert at 6th position that is also fine but after
size plus 1 you can not insert
