Thanks for sharing the solution.. Soooooooper.....
Here are the Questions Assigned By Madam : 
e:
Question 2. Raising a number n to a power p is the same as multiplying n by itself p times. Write a function called power() that takes a double value for n and an int value for p, and returns the result as a double value. Use a default argument of 2 for p, so that if this argument is omitted, the number n will be squared. Write a main() function that gets values from the user to test this function.
Question 4. Write a function that takes two Distance values as arguments and returns the larger one. Include a main() program that accepts two Distance values from the user, compares them, and displays the larger. (See the retstrc program for hints.)
Question 5. Write a function called hms_to_secs() that takes three int values—for hours, minutes, and seconds—as arguments, and returns the equivalent time in seconds (type long). Create a program that exercises this function by repeatedly obtaining a time value in hours, minutes, and seconds from the user (format 12
59), calling the function, and displaying the value of seconds it returns.
Question 6. Start with the program from Exercise 11, Chapter 4, “Structures,” which adds two struct time values. Keep the same functionality, but modify the program so that it uses two functions. The first, time_to_secs(), takes as its only argument a structure of type time, and returns the equivalent in seconds (type long). The second function, secs_to_time(), takes as its only argument a time in seconds (type long), and returns a structure of type time.
