2.2 Programming techniques

1. Syntax

   • an error in the rules/grammar of the language eg missing colon/spelling mistake 

2. logic error

   • the program is writing to do something other than what the programmer intended eg resetting only the first 9 elements in an array instead of all 10

3. run time error

   • more difficult to spot as it can run a program with reporting an error eg runs but doesnt give an output. or the program hangs or becomes inactive 

4. constant

   • value stored in a memory location that never changes within a program

5. Variable

   • Value stored in memory location that can change within in a program

6. Selection

   • where a choice is made in a program depending on a condition or outcome

7. Count controlled iteration

   • Repeats a set number of times 

8. Sequence

   • completing steps in the order which they must happen

9. Condition controlled

   • Repeats unit a condition is met or something in the program changes

10. Iteration

    • Act of repeating specific sections of a code
