- Algorithms
- Pattern/recognition
- Program structures
- Sequence
- Selection
- Iteration
- Psuedocode
- flow charts
- Variables
- Data type
- Casting
- Assign a data type or reassign
- E.g. count = str(count)
- Count=int(count)
- Assign a data type or reassign
- Interger, float/real,string,data
- Casting
- Identifier
- Known by e.g. (name)
- Data type
- Functions
- Call from main program, pass a parameter/argument
- E.g. count(37) - identifier of function - parameter
- Call from main program, pass a parameter/argument
- Tracing a program
- tracetable - write down values of the variables
- Testing
- final
- Iterative
- During development
- SQL
- Select* or frame, move/dob - from = tablename - where = something= a condition
- Types of language - low level(assembly) or high level(pyton)
- Computational thinking
