CS 151: Homework #2  

Problem 1 (From L&L, chapter2 projects) Write an application that reads values
representing time durations in hours, minutes, and seconds, and then prints the 
equivalent total number of seconds (EX. 1 hour, 28 minutes and 42 seconds is 
equivalent to 5322 seconds.)

Problem 2 (From L&L, chapter3 projects)  Write an application that reads the (x,y)
coordinates for two points. Compute the distance between them using the following
formula

	distance = sqrt((x2 - x1)^2 + (y2 - y1)^2 (see the book)

Problem 3 (From L&L, chapter3 projects)  Write an application that reads the 
radius of a sphere and prints its volume and surface areas, where

	volume = 4 / 3 * PI * radius^3
	surface = 4 * PI * radius^2      (see the book)


Include a pseudo code for each problem, and example runs to demonstrate that your 
programs work correctly.
