Fundamentals of Programming - 1.1 - Programming

1.1 - Programming

• 
• Bildunterschrift: Covers Data types, Programming concepts, Arithmetic/Relational/Boolean operations in a programming language, Constants and variables, String handling operations, Random number generation, Exception handling, Subroutines (procedures/functions and parameters), Returning a value/values from a subroutine, Local/global variables in subroutines, Role of stack frames in subroutine calls and Recursive techniques.

1.1.1 - Data Types

• Data Type = an attribute of data which tells the interpreter of compiler how the programmer intends to use the data
• Using the correct data type is important as it:
• makes the code more memory efficient as different data types require different amounts of storage
• makes the code more robust (harder to break and avoids errors) and predictable
• Built in data types (eg. the ones in the mind map) are useful but often limiting so in some programming languages you can also construct your own, more complex "user-defined" data types
• Different Data Types
• Data Types - Arrays and Records
