(b) What is the difference between const char  my*Pointer and char *const my pointer?

(c) Define precondition and post-condition to a member function.

(d) What are the conditions that have to be met for a condition to be an invariant of the class?


2. What is template? Explain about function templates and class templates with  suitable examples.
