1.2.4. Types of Programming Language

Question 1

What are programming paradigms?

Answer 1

different approaches to using a programming language to solve a problem

Question 2

What are the 2 broad catagories which programming paradigms are split into?

Answer 2

• imperative - declarative

Question 3

What are 2 advantages of procedural programming?

Answer 3

1. can be applied to a wide range of problems 2. relatively easy to write and interpret

Question 4

Whate are 2 uses of declarative programming?

Answer 4

1. expert systems 2. ai

Question 5

What are the 4 main structures used in structured programming?

Answer 5

1. sequence 2. selection 3. iteration 4. recursion

Question 6

How does assembly language differ from machine code? (2 things)

Answer 6

• assembly language uses mnemonics rather than binary - one line in assembly language is equal to one line in machine code

Question 7

What is the function of the STA mnemonic?

Answer 7

to store the value in the accumulator at the given memory address

Question 8

What is the function of the BRP mnemonic? (2 things)

Answer 8

1. to branch to a given address if the value in the accumulator is positive 2. it is a conditional branch

Question 9

What is the function of the opcode? (2 things)

Answer 9

• to specify the instruction to be performed and the addressing mode - the operand holds a value, related to the data on which the instruction is to be performed

Question 10

What are the 4 addressing modes?

Answer 10

direct addressing indirect addressing indexed addressing immediate addressing

Question 11

What is a class? (2 things)

Answer 11

• a template for an object that defines the state and behaviour of an object - on object is an instance of a class

Question 12

What are 2 disadvantages of object orientated languages?

Answer 12

1. requires a different style of thinking, which can be difficult for programmers accustomed to other paradigms to pick up 2. generally unsuitable for smaller problems
