Programming

• different languages suit different jobs - developers prefer certain languages

a series of instructions that are executed one after another. follow the pattern: INPUT -> PROCESS -> OUTPUT

sequence, selection, iteration

do one statement after another in the correct order

do a set of statements based on conditions allow your code to make choices- otherwise known as branching

do a set of statements again and again (looping)

repeat a set number of statements a fixed number of times

repeat a set number of statements until a condition is met

a name refer to a particular memory location that is used to store data. The value of the data held in that memory location is not known when the program is written and can change while the program is running

name used to refer to a fixed value. The value is set when the code is written and cannot change while the program is running

a self-contained set of commands that can be called from different parts of the program. returns 0 or many values.

a sub-routine that make take one or more parameters and ALWAYS returns a value

breaking a problem into manageable sections preventing duplicating sections of code when it is needed more than once in a program

easy to read, debug and easy to maintain

integer division

if both inputs are true the output is true else the output is false

if both inputs are true or one input is true the the output is true else the output is false

reverses the outcome of the expression

single equals, sets the value on the right equal to the value on the left

programming languages where the user gives step by step instructions of what to do

a low level language represented by mnenomics which represents the machine code. one-to-one relationship with machine code.

a way to classify programming languages based on their features.

`procedural Object Orientated Assembly

each type of processor has its own unique instruction set
