Interesting. Thanks for the link.

For small applications, I do not think that endl or '\n' will matter much. When you begin writing intensive io applications, it will become very important to have tighter control on your buffering. If you was writing a web application with fastcgi, for example, then it becomes critical to control output. While a web application in C++ is far away from novice level, it's a good idea to start developing understanding of buffering.

#include <iostream.h>

int main()
{

//This prints "Hello World" and <<endl makes a new line
cout<<"Hello World"<<endl;

return 0;
}

Explaination:

"#include <iostream.h>" - This is the header for cout/cin, in other words we include iostream.h so we can use the functions cout<<, and cin>>.

"int main()" - this is where our program actually starts.

"cout<<"Hello World"<<endl;" - This is what actually prints the text to the screen.

Just a simple example !

This is the basic of c++. Every one know about it...
