Comments
Comments are integral part of every program . Comments help in coding, debugging and maintaining a program . The compiler ignores them. They should be used liberally in the program .
In C++, a comment begins with two forward slashes ( // ) and ends with the end of that line. A comment can start at the beginning of the line or on a line following the program statement. This form of giving comments is certainly useful for the short line comments. If a comment continues on more than a line, the two forward slashes should be given on every line.
The C style of giving a comment is also available in C++. This style ( /*....*/) is mainly useful when the comment spans more than a line.
e.g.
void main()
{
/* this is a good old style of giving
a comment. It can be continued to
next line and has to be ended with */
clrscr(); // Clears the Screen
init()_; // Initialize variables.
