C++ How to Program, 10/e

6.21 Wrap-Up

In this chapter, you learned more about functions, including function prototypes, function signatures, function headers and function bodies. We overviewed the math library functions. You learned about argument coercion, or the forcing of arguments to the appropriate types specified by the parameter declarations of a function. We demonstrated how to use functions rand and srand to generate sets of random numbers that can be used for simulations, then presented C++11’s nondeterministic capabilities for producing more secure random numbers. We introduced C++14’s digit separators for more readable numeric literals. We showed how to define sets of constants with scoped enums. You learned about the scope of variables. Two different ways ...
