2.2.1 Programming Techniques

Stopping condition/base case

condition that needs to be met to break the cycle of recursion

Advantages of local variable

Ensures subroutines are self-contained, variable name can be recycled in other subroutines

What is modular programming?

Split large program into small self-contained modules.

Advantages of splitting into sub-procedures

Procedures can be reused, program can be split amongst programmers, speed up completion time by working on multiple procedures concurrently, easier to test modules than whole code

Advantages of concurrent programming

Processes happening at the same time saves time, another task can be completed while waiting for user input for another

Disadvantages of concurrent processing

On a single core processor only one task is actually being processed at once, if tasks are dependent on each other they may need to be completed in order, trying to do a large number of tasks at once means it takes a long time before any of them are individually completed.
