C++ Basics in One Shot - Strivers A2Z DSA
Course - L1
take U forward
This is a full-fledged interview preparation website that I run on my
end so if you 're someone who has three months to like six months of
time left for interviews I will definitely ask you how to check this
Strivers SD sheet. This is one of the most followed resources in the
country as of now what does this resource gives you it gives you 119
well curated problems such that all your DS algo Concepts will be
covered. You should definitely check out coding ninjas because web
development okay data Stitch algorithm foreign County there 's a link
in the description make sure you check them out I 'll be using vs code
in order to code I'll be writing my C plus plus code over here and
whatever the code generates as an output will be produced over here.
In the next video we will be covering Java 1. C plus plus we can use the
hash include so hash include i o stream imagine if you want to use
something like a math dot h I 'll be talking about radical functions
afterwards. C out is a function which exists under the STD and double
colon so in order to use C out you have to write STD.
Program always uses STD for all the functions for most of the functions
you have to write STD double colon double Corner. If you compile it
prints everything now it looks a easier task is n't it so this is how you
can easily write okay now let 's quickly have an input imagine you
want to take an input. It's going to take you a lot of time this is where
C plus plus C is a I 've got something better for you I say can I write
bits STD C plus Plus C plus plus C. It includes all the libraries
everything whatever libraries are there in C plus. plus plus. everything
is included under this bits slash stdc pluscplus plus dot h. We will be
specifically using two data types float and double again they have
ranges depending on the Range that you use you 'll be using float or
double the ranges are visible on the screen. If you want to store bigger
numbers than this this is where something like long long will come in
so if you are saying long long it will give you a wider range.
If we use something like get line inside the get line you have to write
CN what is get line again do not need to dig deep it's an internal
function. The moment you click enter the next line will not be picked
up so it just picks up till the line break so string and get line is used to
take any of the string. Character can store all of the 256 characters in
English dictionary. If we have something like a 10 and that 10 can be
stored in all the three or all the five why can't we use simply long long
or maybe double? Everything takes up a certain space in your
computer so depending on that we decide what to use now integer has
a range now those numbers you can't uh remember so what I usually
do is I keep a rounding of number like I know integer will be from
