I find it useful to include the comment or information about an assertion in the
assert() expression itself.
// Check for invalid oxygen level assert(oxyLevel < OXYGEN_MAX);
can easily be rewritten as:
assert((oxyLevel < OXYGEN_MAX) && "Invalid oxygen levels!!!");
This works because a C string constant is always true (non-zero).
I like the second version since it folds the comment information into the
assert() expression. Also, when the assertion fails, Visual Studio pops up a dialog where you can see the entire
assert() expression (which includes your informative string):
