Robust Programs

Robust Programs

1. Bugs

   • Bugs cause the program to run incorrectly
   • Usually caused by an error in the coding
   • Not all errors will stop a program from running

2. Runtime errors

   • Errors which may cause program errors or the computer to crash
   • There may not appear to be anything wrong with the code
   • They are only detected once the program is executed
   • Examples are running out of memory

3. Syntax errors

   • Mistakes in the way that the code is written
   • Translators can only execute a program if it is syntactically correct
   • Common errors : Spelling mistakes, incorrect punctuation, use of capital letters

4. Logic errors

   • A bug in a program that causes it to operate incorrectly
   • Does not terminate or crash the program
   • Produces unintended or undesired output or other behaviour
