Generalized Rounding

From ComputerScienceOne by Dr Chris Bourke

Concepts

1. How can function pointers point to and call different functions?

   "double x = ptrToSqrt(2.0);\n\nSome more examples:\n\n1 //this pointer can point any function that takes\n\n2 //three arguments: an int, double, and a char\n\n3 //and returns an int value\n\n4 int (*p

2. How can a generalized rounding function round values to different decimal places?

   "Recall that the standard math library provides a round() function that rounds a number to the nearest whole number. We’ve had need to round to cents as well. We now have the ability to write a functi
