1.2.4 Types of Programming Language Flashcards
What are programming paradigms?
Different approaches to using a
programming language to solve a problem.
Which two broad categories are
programming paradigms split into?
- Imperative
- Declarative
State the advantages of procedural
programming
- Can be applied to a wide range of
problems. - Relatively easy to write and interpret.
State a use of declarative programming
- Expert Systems/ Knowledge-based
Systems. - Artificial Intelligence.
Identify the four main programming
structures used in structured
programming
- Sequence
- Selection
- Iteration
- Recursion
How does assembly language differ from
machine code?
Assembly language uses mnemonics
rather than binary. One line in assembly
language is equal to one line in machine
code.
What is the function of the STA
mnemonic?
Storing the value in the Accumulator at
the given memory address.
What is the function of the BRP
mnemonic?
Branches to a given address if the value
in the Accumulator is positive. It is a
conditional branch.
State the function of the opcode and
operand
The opcode specifies the instruction to be
performed and the addressing mode. The
operand holds a value which is related to the
data on which the instruction is to be
performed.
State four addressing modes
- Immediate Addressing
- Direct Addressing
- Indirect Addressing
- Indexed Addressing
What is a class?
A template for an object that defines the
state and behaviour of an object. An
object is an instance of a class.
Give one disadvantage of Object
Oriented Languages
- Requires a different style of thinking which can be
difficult for programmers accustomed to other
paradigms to pick up. - OOP may not be suited to all types of problems.
- Generally unsuitable for smaller problems.
