PROGRAM Rainbow Height Calculator AUTHOR FSU MAIL NAME RECITATION SECTION NUMBER RECITATION INSTRUCTOR NAME COP 3014 Spring 2013 PROJECT NUMBER 1 DUE DATE PLATFORM Windows OS Microsoft Visual C Express 2010 IDE SUMMARY The height of a rainbow can be calculated using very simple formulas Because of the way light is refracted by water droplets the angle between the level of your eye and the top of a rainbow is always the same If you know the distance to the rainbow you can multiply it by the tangent of that angle to find the height of the rainbow The magic angle is 42 333333 degrees C works in radians however so you have to convert the angle to radians with this formula radians degrees PI 180 where PI is 3 141592 The tangent of the angle can then be calculated using the tan function in the C standard library cmath If you multiply the tangent by the distance to the rainbow you get the height of the rainbow You can sometimes see a second fainter rainbow outside a bright rainbow This second rainbow has a magic angle of 52 25 degrees This program asks the user for the distance to the main rainbow and then prints the distance to the main rainbow the height of the main rainbow and the height of the secondary rainbow INPUT OUTPUT The user interactively inputs the distance to the rainbow as an integer in meters The input distance value is printed Then the height of the main rainbow and the height of the secondary rainbow are printed Real numbers are output with three digits of precision ASSUMPTIONS Distance and height units are in meters When asked for a distance value the user types in a valid whole number Error checking does not need to be done on this input value HEADER FILES include iostream standard IO routines include iomanip for output

minutes then 5 000 at a time for the remaining time The professor s pray will kill 50 000 ants only if they reach the 50 yard line then the spray will diminish INPUT The data will be input from the text file provided OUTPUT an intro to each simulation with the stats of the ants will be displayed initially The time ants left yards consumed by ants and the progress of the band and spray
