Explanation

Here we have used cout instead of printf because most popular command form is cout. It has the following basic form:

cout << value_to_be_printed << Value_to_print;

Any number of values can be printed using one command as shown.

The printf command comes from C language. It accepts an optional format specification and a list of variables. Two examples for printing a String are:

printf ("%s", string) ; printf(string) ;

Note that neither methods add a new line. It only prints what you tell it to.
