C++ LANGUAGE WHITESPACE

Whitespace in C++ 


A line containing only whitespace, possibly with a comment, 
is known as a blank line, and C++ compiler totally ignores it. 
Whitespace is the term used in C++ to describe blanks, tabs, 
newline characters and comments. Whitespace separates one part 
of a statement from another and enables the compiler to identify 
where one element in a statement, such as int, ends and the next 

element begins. Statement 1: 

int age; 

In the above statement there must be at least one whitespace 
character (usually a space) between int and age for the compiler 
to be able to distinguish them. Statement 2: 

fruit = apples + oranges;   // Get the total fruit 

In the above statement 2, no whitespace characters are necessary 
between fruit and =, or between = and apples, although you are 
free to include some if you wish for readability purpose.
