>>> 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
