  1. The Role ofVariables By Rishi Magudia

  2. Fixed Value A variable that is initialized at the beginning of the program and isn’t changed thereafter. Is a constant. For example the number of array elements in use.

  3. Stepper • A variable used to move through an array or other data structure, often heading towards a fixed value and stepping through elements in an array. Systematic and predictable

  4. Most recent holder A variable used to record the last thing inserted by a user or a the latest value being read from an array

  5. Most wanted holder The value of a most-wanted holder is the "best" or otherwise the most-wanted value out of the values gone through so far. Example in this case, the higher the number the better it is.

  6. Gatherer The value of a gatherer accumulates all the values gone through so far.

  7. Transformation used to store the result of a calculation involving more than one variable

  8. Follower used to keep check of a previous value of a variable, so that a new value can be compared

  9. Temporary A variable used for storing something for a very short period of time
