We will see how a program runs and what does each line
mean in this lecture. This is how the compilation process
work So it is compiler which makes it possible for us to
run a source code. Coding Ninjas has supported us in
providing this amazing DSA course to you. . you need an
IDE to write, run and execute a code. There are many
IDEs out there - CodeBlocks, VsCode and many more -
which you do n't even need to install Replit is one of
them. You can directly create a C++ there and run it using
Replit. In C++, many namespaces are there which have
cout functions in them so if we want to use cout , we
have to add this file to our code. We use these signs to
output the result into standard namespace. If you will
use > > by mistake by mistake, then it will give you
compilation error So we use this operator to display
output.
We are going to talk about data types and variables.
Whenever you have to story any information or data in
the memory. You have to mention what type of data it is
and how much memory it will take. For eg- int a = 5, a is a
variable in memory which is of int type and it has value 5
in it. We have certain rules which we have to follow
when we are giving names. There is a function named
sizeof , which will tell you about the space being used by
