Programming
- Algorithms
- Solving
problems 1
step at a time
- Processors can
only process 1
instruction at a
time
- Mainly expressed
as a flow chart
- Symbols
- Symbols
- Solving
problems 1
step at a time
- Pseudocode
- Used for planning algorithms
- Should allow a programmer to
write it in any language
- Key words written in capital letters (eg INPUT,IF, WHILE)
- Used for planning algorithms
- High Level/ Low Level Programming
- Low Level is
understood by
the processor
- Machine Code
- binary codes for each
instruction and register
location
- binary codes for each
instruction and register
location
- Assembly Language
- Code specific to a type of processor
- eg INP, LDA, Out
- eg INP, LDA, Out
- Code specific to a type of processor
- Machine Code
- High Level has to
be translated
- Uses languages that is easier
to understand by humans
- eg Python,
BASIC,
Javascript
- Uses languages that is easier
to understand by humans
- Low Level is
understood by
the processor
- Translation
- Assembler
- Turns assembly language into
machine code
- Only can be used in low
level programming
- Turns assembly language into
machine code
- Compiler
- Creates an executable file to
run the program
- Once is compiled it
doesn't need the original
source coe
- Would be used for
proprietary software
- Creates an executable file to
run the program
- Interpreters
- Executes the source code directly
- Used when creating a program
- Would be used on open source software
- Executes the source code directly
- Assembler
- Control Flow
- Sequencing
- The order through an algorithm
- The order through an algorithm
- Selection
- IF THEN ELSE to control the flow
- IF THEN ELSE to control the flow
- Iteration
- WHILE or FOR
Loop
- WHILE or FOR
Loop
- Sequencing
- Data Types
- Variables or constant
- Variable changes
during the program eg
score
- Constant stays the
same eg Pi
- Variable changes
during the program eg
score
- Integers and real numbers
- Integer is a whole number
- Read (sometimes called
float) can have decimals
places
- Integer is a whole number
- Arrays are lists if
the same type
- Operations are
mathematical symbols
eg < > = + - * /
- Variables or constant
- Testing
- Logical error
- Human error with the
construction of the
algorithm
- Human error with the
construction of the
algorithm
- Run-time error
- An error in the
program eg stuck in
the loop
- An error in the
program eg stuck in
the loop
- Syntax error
- Not a correct command
for the coding language
being used
- Not a correct command
for the coding language
being used
- Logical error
