Notes
- 1.
I’m lining up the =’s, you’ll notice. Neatness makes for easier reading.
- 2.
There are maybe too many ways to declare constant values in C++: const, enum, constexpr, inline constexpr, static const...but we’ll get to that later.
- 3.
If you want to add 1, rather than some other number, there’s a special “increment” operator just for that:
++seasonsOfAmericanIdol;
We’ll see that again in Chapter 5, along with “decrement” (--).
- 4.
Include files inherited from C++’s ancestor C, under current conventions, start with a “c”: cmath and cstdlib, for example.
- 5.
We cast to int to avoid that conversion warning mentioned in the preceding “Antibugging.” The time function returns a time_t (whatever that is); we’ll force it to be an int.
