What is a programming paradigm
The approach a programming language takes to define a program.
What are the different common types of high-level paradigms
- Procedural programming
- Object-oriented programming
- Functional programming
- Declarative Programming
What is procedural p[rogramming
A language where instructions are given in sequence.
These can be grouped into subroutines that can be called throughout the program.
What is object-orientated programming
A language in which the solution is represented by objects that interact
What is functional programming
A description of the solution to a problem is built up through a collection of functions, some of which are used to define other functions
What is declarative programming
A language where the characteristics of a solution are stated, rather than stating how the problem is solved
Eg. SQL
How do procedural languages work
We give the compiler instructions on the steps we want it to go through to solve a problem.
- These instructions are given in sequence
- Selection is used to decide what a program does when certain conditions are met
- Iteration (ie. loops) dictates how many times it does it
What are the two types of iteration
- Condition controlled
- Count controlled
What is memory addressing
Different ways of referring to locations.
what does ADD do (LMC)
Add
What does SUB do (LMC)
subtract
What does STA do (LMC)
Stores value from the accumulator to memory
What does LDA do (LMC)
Loads value from the memory to the accumulator
What does BRA do (LMC)
Branch always ( loop continuously)
What does BRZ do
Branch if zero ( loop only if the value in the accumulator is currently 0)
