(This is a better version of an exercise from Chapter 1.) A government research lab has concluded that an artificial sweetener commonly used in diet soda pop causes death in laboratory mice. A friend of yours is desperate to lose weight but cannot give up soda pop. Your friend wants to know how much diet soda pop it is pos- sible to drink without dying as a result. Write a program to supply the answer. The input to the program is the amount of artificial sweetener needed to kill a mouse, the weight of the mouse, and the desired weight of the dieter. Assume that dietsoda contains 1/10th of 1% artificial sweetener. Use a named constant for this fraction. You may want to express the percent as the double value 0.001.
