The "fields" in a struct are also called "members"

struct Workout_S
{
  char date[DATE_LEN];
  int meters;
  double splitTimeSeconds; // store the field in pure seconds
  int minutes;
  bool personalRecord;
};

The members are date, meters, splitTimeSeconds,
   minutes, personalRecord.

Declaring a struct allocates NO MEMORY.

Only when you use the struct to declare a variable
is any memory allocated, e.g.

 Workout_S myWorkout;  // scalar

 Workout_S januaryWorkouts[31];  // array


Scalar means "a variable that only holds
   a single value, i.e. not an array"


***

Be careful with strcpy... if you copy a long string into a short
target, this is called a buffer overrun.

Google buffer overrun, and you will be led to stuff about
 exploits...  that is ways to break into systems, hacker stuff.

Emacs tricks

 Ctrl/X 2  gives you two windows (vertically,one on top of other)
 Ctrl/X 1  reduces to one window (keep the one you are in)
 Ctrl/X 0  zeros out the current window (leaving the rest)

 Ctrl/X 3  gives you two windows side by side

switching between windows...

  if you have a mouse just click in the dest window..

  but if you are using secure shell on a PC, you can't use the mouse,

  so use CTRL/X O  (letter O, stands for "other window")
