Operator Overloading

• Some is common (e.g., + for int and float)

• Some is potential trouble (e.g., * in C and C++)

• Loss of compiler error detection (omission of an operand should be a detectable error)

• Can be avoided by introduction of new symbols (e.g., Pascal's div)

• C++ and Ada allow user-defined overloaded operators

• Potential problems:
  • Users can define nonsense operations
  • Readability may suffer
