Answer Posted / achal ubbott
OK! this is a set of questions. Let me see how far can I go.
1. destructor of a class can be called explicitly as
follows using the object of the class.
sample * p = new sample(/*some arguments*/);
p->~sample(); // explicit call;
3. correct order of destructor call is ~derived() and then
~base().
in case you haven't declared the destructor of base as
virtual then delete base; would cause problems.
cheers

Question: Write a program that prints a paycheck. Ask the program user for the name of the employee, the hourly rate, and the number of hours worked. If the number of hours exceeds 40, the employee is paid “time and a half”, that is, 150 percent of the hourly rate on the hours exceeding 40. Be sure to use stepwi se refine ment and break your solution into several functions. Use the int_name function to print the dollar amount of the check.
