What Is Tokens


   >>> The Smallest individual units in a program are known as tokens. Tokens ate usually separated by "white space."

   C++ has the following tokens:

     >>> Keywords.
    >>> Identifiers.
    >>> Constants.
    >>> Strings.
    >>> Operators.

   A C++ program is written using tokens, white spaces and the syntax of the language.
    Example:

                   a = i + + + j;

                  The Programmer who wrote the code might have intended either of these two statements:
                a = i + (+ + j)

                 a = (i + +) + j

Example 5 : Demo Of Cin And Cout.


   >>> Example 5 : Demo Of Cin And Cout.

            #include<iostream.h>
           #include<conio.h>

           void main()

                   {

                     int a=0,b=0,c=0;

                     clrscr();

                     cout << "Enter a and b ->";
                     cind >> a >> b;

                     c = a + b;
                     cout << "\n Ans = "<<c;

                     getch();

                    }

   >>> Output :

            Enter a and b -> 5 6
           Ans = 11

Standard Input ( cin )



   >>> The standard input device is usually the keyboard.

   >>> Cout is used in conjunction with the >>. The operator  >> is known as extraction or get-from operator. The operator must be followed by the variable that will store the data that is going to be extracted from the stream.

   >>> Cin is an object, predefined in C++ to correspond to the standard input stream. This stream represents data coming from the keyboard.

   >>> The >> takes the value from the stream object on its left $ places in the variable on its right.

   >>> For example :

                                int age;
                                cind >> age;

   >>> The first statement declares a variable of type int called age and the second one waits for an input from cin ( the keyboard) in order to store it in this integer variable.

   >>> Cin is an object, predefined in C++ to correspond to the standard input stream. This stream represents data coming from the keyboard.

   >>> The >> takes the value from the stream object on its left $ places in the variable on its right.

   >>> For example:

                              int age;
                              cin >> age;

   >>> The first statement declares a variable of type int called age, and the second one waits for an inputs from cin (the keyboard) in order to store it in this integer variable.

   >>> Cin can only process the input from the keyboard once the RETURN key has been pressed. Therefore, even if you request a single character the extraction from cin will not process the input until the used presses RETURN after the character has been introduced.

   >>> You must always consider the type of the variable that you are using as a container with cin  extractions. If you request an integer you will get an integer, if you request a character you will get a character and if you request a string of characters you will get a string of characters.

   >>> You can also use cin to request more than one datum input from the user:

                           cin >> a >> b;

                     is equivalent to :

                            cin >> a;
                            cin >> b;

   >>> In both cases the user must give two data, one for variable a and another one for variable b that may be separated by any valid blank separator: a space, a tab character or a newline.
