Assignment 4

In New York, earthquakes are primarily events we hear about rather than experience. The Richter scale for measuring earthquake intensity is logarithmic; a 5.0 earthquake is ten times as intense as a 4.0 earthquake. You'll be writing a program to compare earthquakes. If quake1 and quake2 have Richter values richter1 and richter2, then you can compute the relative magnitude and energy using these formulas:

relative magnitude = 10richter1 - richter2
relative energy = 30richter1 - richter2

Write the function prototyped here: 

    void compareQuakes(double richter1, double richter2,
                       double& relMagnitude, double& relEnergy);

Then use it in a program that lets the user input Richter values for two earthquakes and reports the relative magnitude and intensity. Here's some sample data for testing:

Quake 1: Southern Alaska, 1964
Quake 2: San Francisco, 1906		 8.5
8.3		 Quake 1 was 1.58 times the magnitude of Quake 2
and released 1.97 times as much energy.
Quake 1: Northwest Iran, 1990
Quake 2: Central Mexico, 1985		 7.7
8.1		 Quake 1 was 0.40 times the magnitude of Quake 2
and released 0.26 times as much energy.
Quake 1: Shaanxi Province, China, 1556
Quake 2: Los Angeles, 1994		 8.6
6.6		 Quake 1 was 100 times the magnitude of Quake 2
and released 900 times as much energy.
