Throw Error#

The throw statement can take in various error types for instance out_of_range exceptions.

Try/Catch#

try {
  ...
} catch (some_exception& err) {
  ...
} catch
...

No Exceptions#

If a function should never throw an exception, noexcept can be declared:

void f(Type arg) noexcept {
  ...hyugbfdrctkuj,hygtfrbndenswacq CZCXCB WQ
}

Alternatives#

Alternatives to throwing an exception are:

  • Returning a failure value (e.g., false, 0)

  • Terminating the program (e.g., terminate(), exit(), abort())

Static Assert#

An assertion can be checked during compile time for various constant/static objects using the static_assert function.
