1. Programming techniques

   • Data types
     • Real/float
       • Number with decimal point
     • Integer
       • Number without a decimal point
     • String
       • A series of characters/TEXT
     • Character
       • A single letter or symbol
     • Date/Time
       • Date and time in any format
     • Boolean
       • Yes no, true false value
   • Syntax error
     • An error in the rules/grammar of the language e.g. a missing colon or spelling mistake
   • Logic error
     • The program is written to do something other than what the programmer intended e.g. Resetting the first 9 elements in an array instead of all 10
   • Run time error
     • More difficult to spot as it can run a program without reporting an error e.g. runs but doesn't give an output. Or the program hangs and becomes inactive.
   • Sequence
     • Completing steps in the order which they must happen
   • Selection
     • Where a choice is made in a program depending on a decision or outcome.
