What is the difference between operational and programmer errors?

  1. A Operational errors are expected runtime problems to handle; programmer errors are bugs that should crash the process
  2. B Operational errors are bugs; programmer errors are recoverable
  3. C They are the same
  4. D Programmer errors only occur at compile time
Answer

Operational errors are expected runtime problems to handle; programmer errors are bugs that should crash the process
