Programming

1. High level Languages

   • Code written similarly to human language.
     • Java
     • Pascal
     • COBOL
     • C#
     • C++

2. Machine code

   • Not like human language, made of bit patterns

3. Variables

   • Store data that can change
   • Local variable
     • Is defined within a sub procedure and as such is only accessible from within that same sub procedure. This is known as its scope.
   • Global Variable
     • has a larger scope as it is defined globally and is therefore accessible from anywhere within a program
   • Static Variable
     • Stored in a location in memory and have a lifespan that lasts the entire time that program is running
   • Dynamic
     • Each time a dynamic variable is defined, it is assigned a new location in memory and has a lifespan that ends when the sub procedure in which it was defined ends.

4. Constants

   • Store data that does not change

5. Assembler

   • Assembly code > opcode

6. Interpreter

   • High level language> Machine code

7. Compiler

   • High level languages>Machine code

8. Types of errors

   • Syntax
