PROGRAMMIMG TECHNIQUES

1. Techniques Constant Value STORED IN A MEMORY LOCATION that never changes WITHIN A PROGRAM

2. Variable Value STORED IN MEMORY LOCATION that can change WITHIN IN A PROGRAM

3. Sequence: Completing steps in the order which they must happen

4. Selection: Where a choice is made in a program depending on a condition or outcome

5. Iteration: Act of repeating or lopping specific sections of code

6. Count controlled Iteration: Repeats a set number of times

7. Condition controlled: Repeats until a condition is met or something in the program changes

8. Errors

   • Syntax Error An error in the rules/grammar of the language Eg missing colon / spelling mistake
   • Logic Error The program is written to do something other than what the programmer intended Eg Resetting only 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 or Becomes inactive
