Hello students, Welcome to second video
In this we see how to program through code blocks
and specify about some Keywords
Start with a basic program
first, we create a project
then look for console application
C++
look for file location
Name the project
check the button below
sometimes you would find the blank screen
in file menu look for manage
might be possible the cursor would be scrolled
Dont get panic
 
then source projects
by default program is of HELLO World
there is a difference between compilers
as specified in book the compiler is Turbo C++
in which there  name stream is not present
the keyword of integer character or float, or can say  data type
due to the bit version of computer
In inheritance chapter you might ask for byte
let move to first program
compiler starts the program from here
discuss about main function
main function is present in all programming language
in c, c++, java
 
It call the operating system and from hardware it take
permission. to execute a process
function is to operating system
now compiler move to cout
compile first in from the main function
then check for what is cout
cout is a object
might not confused with keyword
but it is a object
of iostream.h file
there are other as well we will continue later
let move forward
this is a c error
it work same as object
c log also work the same
not concern about it
just keep in mind as a object
to run the program built+ run
through cout is the output
Hello world
and which comes through c error
is c error
and through c log is c log
same cin is the object through which we take input
object of the stream file
further is something about machine language
project is saved as d.c++
go to my computer D drive then c++
there will an object file
main.obj
is a machine language file
in bin there will be a exe file
which show the output in black screen
So this is all process
then we will continue latter part in other video
and typecasting part ahead
class inheritance, file handling, array
please subscribe, share, and for doubt please comment below
thank you!
