programming language c++,write a program to print hello word,write a program to sum two numbers in c++

if you want to lean about more about programming languages click here programming  langages

click here for history of c c programming

so lets get started

here you can get video lactures as well as codes to understant the coding

c++ is high level language used for programming  it is derived from c language. c and c++ both are power full languages and used for simulation ,gaming etc...c & c++ both have simple syntax and easy to learn

we will study about

introduction programs

condition statement(if, if  else ,nested if else)

loops(while, do  while ,for loops, nested loop)

arrays(one dimensional, two dimensional array, three dimensional array)

pointers 

file handling(read write operations)

introduction to c++

hello word

it is first program in which #include is used to include predefined function that is already define in c or c++ library iostream is used input output stream used to print massage on sucreen or to take input from user. if we not write using namespace std we need every time to write std:: using cin or cout command

cin>>

it is used to take input from user

cout<<

it is used to print massage of screen

data types in c++

•int data type used for integer value for example 1,3,5, 10 etc..

•Float data type is used for point values

•Char is used for character used to take any kind of value charecter float int etc.. or used to store one character.

•String data used for character is "any thing we write" is store in string

hello word is program is to print massage on screen

now we take two numbers from users 

in this program we display massage of screen to enter number and then create third  sum variable to calculate addition of numbers and then display sum.
