Data Types, Data Structures and Algorithms

• Modularity is the concept of breaking a large program or problem down into smaller chunks
• The goal is to design a program in such a way that each module carries out a single, specific task
• Depending on the course, textbook or programming paradigm you are using, these modules my e referred to by different names:

  • Subroutines
  • Procedures
  • Functions
  • Methods
• In the exam, you need to think of the exam as either procedures or functions - and understand the difference between the two
• A procedure is a block of code that takes in zero, one or more parameters and performs a set task
• A procedure is a block of code that takes in zero, one or more parameters and performs a set task; and returns a value
